Vetted JavaScript developer in the United States (UTC-6)

My diverse skills and background have given me unique abilities to identify and resolve logic issues in both humans and technology. With over ten years of experience in software engineering and engineering management/leadership, I have effectively collaborated with cross-functional teams and stakeholders to develop software solutions and assist organizations/businesses in achieving their goals and objectives. I absolutely love what I do. It is my passion, inspiration and adventure. I believe the recruiting team at my previous employers are intentionally preventing me from being employed, as evidenced by the issues I've presented. Such discriminatory hiring procedures and actions are illegal, unethical, and violate my right to work and equal opportunity.

Some screenshots of technical issues I sent you were taken on December 17/24. Since I began being interviewed at JPMorgan last year, the answer to my job applications has been severely delayed, often for weeks or months. I need to refer back to the job post when a recruiter contacts me.It's not about job competition. It's about an **unfair, unethical, dishonest and biased** hiring process, as well as punishment for speaking up about it and concealing the faults of laying me off by preventing me from being hired again.  I never received answers to the following issues, which I raised in the summer 2024, but the issues have gotten worse and doubled down.I documented all issues and difficulties I encountered.  I also sent you a separate email about the incident. To summarize, please review all of the issues below that have taken away my job opportunities and blocked me from being hired. Please address the concerns and eliminate unfair, dishonest, and biased hiring practices, as well as the hate and retaliation attempts, or forward them to your supervisor or the appropriate department for resolution..Thank you!Best,QiongThe following issues were escalated to JP Morgan Chase Employee Relations on 09/09/24.1. Why was the quality of your interviews low? Include the recruiter’s name, date of interview, comments made or questions asked, etc.Here is an example of a low-quality interview in which the interviewer is rude, irrational, unprofessional, unfair, threatening and full of hatred.I was not advised that a coding interview would require me to share my computer screen. The interview was originally set for 30 minutes, and I was told it would be with a hiring manager, who is typically a non-technical person based on my previous interview experience at JPMC.   Also, 30 minutes is too short for a coding session. So I didn't join the interview from my computer but my phone. On May 6, 2024, at 7:41 AM, the recruiter contacted me via email, saying,  “The manager has requested to extend the interview an additional 30 minutes..”  See the following. When I woke up and received his email, it was less than an hour till my interview, and I still didn't know if there was a coding round that needed me to show my screen.Then **Dhira Kaleeswaran** and another individual joined the zoom.  I was informed that another individual without her camera on will conduct the coding interview for **Dhira Kaleeswaran**. They required me to share my computer screen.  Asking candidates to share their screen for a coding interview without giving advance notice is very disrespectful about the candidate's data privacy and security.  I was shocked that she works in the security domain, yet doesn't seem to care about others' data privacy and security. I have taken numerous professional technical coding interviews, including FAANG, and I have never been asked to share my screen, let alone share it without giving notice.Not only am I uncomfortable sharing my screen unprepared in an unsafe manner, but I also had an internet connectivity issue with my computer, so I asked Dhira Kaleeswaran if I could reschedule. She started to blame me and nearly yelled at me during the interview for not being able to join the Zoom coding session from my computer because of technical difficulties.  She even unreasonably brought the HR interview scheduler on the call to try to resolve my wifi issue.  She was rude and insane, suggesting that I either complete the interview today no matter what or be removed from consideration. Of course, the HR scheduler had no idea how to address my wifi issue. Like me, she didn't seem to know what this interview was about or what needed to be prepared for the interview. As a result, the interview couldn't proceed and couldn't be rescheduled, my application was no longer being considered. I received the rejection email almost immediately after I got off the zoom call with them. I’ve never met her before and knew nothing about her. There is no reason for her to act crazy like a hater, unless she was told to.Hi Qiong,The manager has request to extend the interview an additional 30 minutes. Just wanted to keep you posted on this. Please keep in mind that they may not need the full hour however they wanted to extend the interview just in case.Thanks,Joseph Carrion |Senior Technology Recruiter - Global Technology Recruitment JPMorgan Chase & Co. | Dallas Corporate Center – Legacy West Joseph.Carrion@JPMChase.com| 214-263-12032.  When and who asked you the following questions: where were you born and what do you like to do when you are not working? What role were you interviewing for?The question “where were I born?” was asked by the interviewer Srinivas R Alla, Vice President Sr Lead Software Engineer at the interview for the position 210487013 / Senior Lead Software Engineer - Infrastructure / Plano TX / JPMC[https://jpmc.fa.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX\_1001/job/210487013/?utm\_medium=jobshare](https://jpmc.fa.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX_1001/job/210487013/?utm_medium=jobshare)Monday April 22 20243:00 PM – 4:00 PM CT**Srinivas R Alla**Vice PresidentSr Lead Software EngineerSenior Lead Software Engineer - Infrastructure (210487013)**Via Zoom App**: Enter Meeting ID 994 4716 5504**Passcode: 020524DateTimeInterviewer(s)Requisition title and numberVideoconference**FridayAugust 9, 20243:00 PM – 3:45 PM **CENTRAL TIMEThomas M Pratt**(He/Him/His)Executive DirectorDirector of Security Engineering**Michael Ringer**Vice PresidentSr Lead Cybersecurity ArchitectLead Security Engineer (210500411)**Via Zoom App**:  Enter Meeting ID **992 4944 3175Passcode: 020524**4. Any other examples where interviews were biased or you were treated unfairly?Aside from the other reasons/examples stated in the answers to the rest of the questions 1, 2, 3, 5, 6: The quality of my interviews is low. The hiring process was delayed, resulting in positions being filled before my interview could begin. My candidacy was dropped, and my scheduled interviews were canceled without explanation on the interview day, even though I had already joined the Zoom call and was about to begin my interview. Here are three additional examples:A. Someone from the HR department changed my applicant profile and employment history at JPMC.  I was employed as a VP with full-time employment in 2021 and I was NEVER hired as a contractor or associate engineer, but I've been informed by multiple recruiters that they saw my profile as an associate engineer and a contractor.  I've been applying for jobs at JPMC almost everyday and always have a current resume on my profile, so why has my employment history become something else that I have never put on my resume? Who did that?B. I no longer receive updates on my interview status. I have not heard back from any recruiters on the interviews I had since June 2024. When I asked when I could expect to hear the interview results, one of my interviewers said they didn't know because once they made the selection, it's up to HR to decide when to arrange the next round.  I could have been selected from any earlier interviews, but they never kept me updated and scheduled the next round, thus I was never moved forward. I wrote multiple emails to [vernadette.j.caga@jpmorgan.com](mailto:vernadette.j.caga@jpmorgan.com) and [stephanie.colunga@jpmchase.com](mailto:stephanie.colunga@jpmchase.com) asking about application status but did not receive response.C. Furthermore, there are strong indications that someone is attempting to keep me from being hired by undermining teams who wanted to interview me by purposely delaying their interview requests until after I have responded to any additional unexpected requests in order to send me to interviews where interviewers will never choose me at all. They've been doing this for months. The same pattern appears repeatedly. It's difficult to believe it wasn't true.D.  Interviewers do not appear to be qualified for the positions for which they are conducting interviews. The most recent example is that I was scheduled for an interview for a Senior VP position (210540185 | Senior Lead Software Engineer - Python) with an interviewer whose job title is an associate engineer, not even a VP. Please see the interview info below. How can someone make a good hiring decision for a position he or she does not have enough experience with? The only explanation is that the aim of this interview is to reject me rather than hiring me. I believe that this is also the cause for the poor quality of my recent ongoing interviews. My questions are, who sent an associate engineer to interview for a VP position, and why?5. Who would not respond to you after offering a week of your availability?Many of my interviews were scheduled at the end of the last available day I provided, leaving me with no time to prepare for the interview. I sometimes have to email the recruiter again to see if my availability is still working for them after not hearing back from them till the end of my last available day. Not every interview is scheduled once I give my availability, and there's no explanation. Most recruiters do not contact me directly to explain roles or answer questions. Most of the time, schedulers send me an interview request inquiring for my availability without telling me who the recruiter is. Sometimes my provided availability was totally ignored without explanation. My interview was delayed to be scheduled, and they chose a day at random without even asking about my new availability.I gave my availability from 6/26/24 to 6/28/24, 10am - 4pm CDT  to the recruiter Guzman, Trisha" <[trisha.guzman@chase.com](mailto:trisha.guzman@chase.com)\> , but the interview was scheduled on 07/03/24.

Thank you!I've had at least 20 interviews at JPMC since March 2024, but the quality of the interviews and recruitment process has continuously deteriorated. Now it is highly unprofessional and biased, which results in me losing numerous opportunities, financially and mentally suffering because I'm putting so much time and money into preparing the interviews for months and months yet being unfairly treated in the hiring process, leading me to believe that I was purposefully blocked from being hired by HR personnel due to my prior employment at the JPMC, as I was laid off for no apparent reason shortly after receiving a performance raise for resolving a critical technical issue in three days that no one had been able to resolve for a year.Here are some of the issues I have experienced:1.  Interviewers do not appear to be qualified for the positions for which they are conducting interviews. The most recent example is that I was scheduled for an interview for a Senior VP position (210540185 | Senior Lead Software Engineer - Python) with an interviewer whose job title is an associate engineer, not even a VP. Please see the interview info below. How can someone make a good hiring decision for a position he or she does not have enough experience with? The only explanation is that the aim of this interview is to reject me rather than employ me, but whoever assigned this associate engineer to interview for a senior VP position couldn't find a manager or engineer willing to lie for him or her throughout the interview and reject me. I believe that this is also the cause for the poor quality of my recent ongoing interviews.

The quality of my interviews are extremely low, with the clear purpose of removing my candidacy. Despite having had over 20 interviews, the majority of which were for technical roles, there are very few technical interviews. Most of the time, I've been interviewed and rejected by interviewers that don't have a software engineer or any other technical experience, with questions like "where I was born" and "what do I like to do when I'm not working". At some interviews, the interviewer's questions and description of job requirements are completely different from the requirements in the job posting, which fits great in my experience.3. Delayed hiring process, resulting in positions being filled before my interview even begins. The delay is usually somewhere between 1- 4 weeks.  After offering a week of my full-day availability to the recruiter or scheduler who requested, I may not hear anything back.  If you check in with them, they may or may not inform you that they need you to update your availability in the last minute of your provided availability.4. My candidacy was dropped, and my scheduled interviews were canceled without explanation on the interview day when I already joined the Zoom call and was about to have my interview .5. Someone in your department changed my applicant profile and employment history at JPMC.  I was employed as a VP with full-time employment in 2021 and I was NEVER hired as a contractor or associate engineer, but I've been informed by multiple recruiters that they saw my profile as an associate engineer and a contractor.  I've been applying for jobs at JPMC almost everyday and always have a current resume on my profile, so why has my employment history become something else that I have never put on my resume? Who did that?6. Strangely, recent interview requests beginning in April 2024 have consistently requested at the same time. There are always two or more requests that follow one another closely, almost as if they are competing. If I didn't move forward with one of them, the other interview requests would disappear.7. I no longer receive updates on my interview status. I have not heard back from any recruiters on the interviews I had in June 2024. When I asked when I could expect to hear the interview results, one of my interviewers said they didn't know because once they made the selection, it's up to HR to decide when to arrange the next round. Could you help update my interview status for all the interviews I had back in June 2024?For item 2 - 7, I can provide more details and examples with 5W(who, what, where, when, why) and 1H(How) if neededThe problems got worse. I continue to experience unprofessional, biased, dishonest, or even scam-like processes.📷**devqm** <[prowork.dev1010@gmail.com](mailto:prowork.dev1010@gmail.com)\> Nov 8, 2024, 11:06 AM📷📷📷to Anish📷Hi Anish,I wanted to follow up on our last communication about the issues I encountered during the hiring process. You advised me that I would receive a response in a few weeks, but it has been more than 2 months(3 months since submitting my initial request) and I still have not received anything. I'm wondering if you have any updates?  I'm still experiencing issues with the hiring process. See below.Last week, Trisha Guzman, the recruiter called me on the phone.  I was stunned when she said my name as "Qiong Michaels Jeremy." I had previously mentioned in my email that someone had modified my employment history, but now it appears they've also changed my name in my profile as well? Had she not seen my resume? I've spoken with countless recruiters throughout the years. Never before has anyone called me without even knowing my name. I'd think she received incorrect information somewhere. Where is the incorrect information from?Also, the job description was removed prior to the interview, but I was not provided any information other than the job title for which I am interviewing. My interviewer informed me that I was interviewing for a position on the forensic team. I don't recall seeing any job descriptions for the position I applied for that mentioned forensics. Despite the fact that the interviewer stated that this is still an engineering role and that I answered his questions well, I'm still concerned if the job description was changed on the fly, so the add-on forensic topic would be used as an excuse to reject me. I have not heard back from the recruiter after the interview.Since I was wrongfully laid off in 2022, I've been applying for most software engineering-related positions almost every day, at least once a week or two, for about two years, and I have over ten years of experience, as well as so many teams(around 20-30) interested in interviewing me, how could I not be qualified for anything and be hired already? Are they all mistaken in selecting me, or are there HR personnel that continually prevent me from being hired?  Which one is more obvious to you? There are also other leadership positions on the development team. Why have I been repeatedly denied for those positions and instead selected for positions where I barely have expertise?Based on the issues I raised in my previous email and above, it has occurred to me that individuals deliberately preventing me from being hired by the firm are most likely working at the Human Resources department.  Because none of the technical teams I interviewed for knew me, why would they reject me on purpose for no reason? The only individuals who knew me from the start (Even though I didn't know anyone at HR when I worked there, I wasn't sure why they wanted to fight me, unless they were some horrible soulless individuals who would hurt anyone to spread their hatred and jealousy) were the ones who wrongfully laid me off, and they have yet to be held accountable for what they did.  Because if they had, they would have stopped blocking from being hired already.I would appreciate it if the firm can sort this out and stop such dishonest, unkind and aggressive behavior directed at me and possibly other employees. I still hope the firm will change for the better, and I would like to return to work.  Could you please let me know when I can expect an answer?  Thank you.devqm <[prowork.dev1010@gmail.com](mailto:prowork.dev1010@gmail.com)\> Nov 12, 2024, 6:34 AM to Anish Hi Anish, Could you please explain how each of the submitted issues was addressed by Employee Relationships? Since I submitted the request, the frequency of being selected for interviews has dropped dramatically from every week before to only one in the last 3 months, and some of the issues I submitted appear to be worsening rather than improving. In my most recent conversation with a recruiter Trisha Guzman, the recruiter called me with the wrong name on my candidate profile. How did this occur? Can you explain it in detail? Thanks.

(see the email below or the attachment).  He did not respond until two days later with the email below, attempting to blame me by pretending I was not available for the interview.  Is there anything you can do to stop such hostile behavior? I don't even know him and anyone else working in your HR department. Why do they keep sabotaging my interviews and attacking me? Best, Qiong devqm <[prowork.dev1010@gmail.com](mailto:prowork.dev1010@gmail.com)\> Attachments Jan 13, 2025, 9:22 AM to Anish Hey Anish, I no longer can see the positions I applied for.  My candidate profile page no longer works.  What is happening?  I received a server error message stating "Something went wrong.Try again later." It's been there for weeks now. Please see the attached screenshots. devqm <[prowork.dev1010@gmail.com](mailto:prowork.dev1010@gmail.com)\> Attachments Jan 27, 2025, 10:06 AM (22 hours ago) to Anish Hi, I wanted to follow up with the profile issue I had earlier. It is still not resolved. I'm not able to see job applications on my candidate profile. See attached screenshots.  Furthermore,the recruiting has become worse, and it seems to be a scam. Despite providing my availability to the recruiter months ago, and the recruiter stated she will send an invite for an interview, my interview was never scheduled. Instead, I just received a rejection email indicating they had interviewed me and thanked me for meeting them?!!!! Best, QiongDuring my most recent interview, It seemed the interviewers did not see my resume. They didn't even know my name and called me **"Michelle"**. Of course, they had no idea that I specialized in software development. Three people asked me the same question. I explained three times, saying, "I developed features, fixed bugs, and resolved any production issues for the applications," which is standard software development practice, so the hiring manager would at least know if they were looking for a senior lead software engineer . However, they did not appear to have read my resume or even known I'm specialized in software development. After I had answered the same questions three times, one of the interviewers finally understood it was an agile process.They appear to be hardware professionals working at a data center. I'm surprised I was chosen for a data center position in which I may not have any prior experience. However, HR has done it before, most recently sending me to an interview for a digital forensics position. But I have not been interviewed for any software development positions, particularly in Python, where I have extensive knowledge and experience.One of the recruiters informed me that they could not offer me a salary as high as my present rate as a software developer lead since the position was not in software development. An analogy for this type of unethical recruiting scam would be terminating doctors and then asking them if they want to work as waiters or have no job . Are we truly short on skilled software engineers and need to look for them abroad while wrongfully laying off experienced good engineers and preventing them from being hired through **unethical dishonest biased** recruiting process? I fixed technical issues generated by the engineers abroad due to a lack of expertise in my previous position at JPMorgan, yet I was laid off shortly after that. They still had jobs after I was laid off.  Please explain why?Interview for SR Lead Software Engineer - JPMorgan Chase InboxSearch for all messages with label InboxRemove label Inbox from this conversation📷**Interdonato, Brian M **📷Tue, Jan 21, 9:40 AM (7 days ago)📷📷📷to me📷**Jan23Thu**Interview for SR Lead Software Engineer - JPMorgan Chase[View on Google Calendar](https://calendar.google.com/calendar/r?eid=XzY4bzM0ZDlnNjRwMzJsMWg2c3BqMGMxamI4bWppZGhqNm9zamlkcGg2Y3JqY2czNmNrczMwZWhnNzhvM2tjMXE2Y3E2Nm85cWM1aDZjcGhxY3BpajJwaHFjaGdqY29iNWVoazMwIHByb3dvcmsuZGV2MTAxMEBt&ctok=cHJvd29yay5kZXYxMDEwQGdtYWlsLmNvbQ)WhenThu Jan 23, 2025 10am – 10:45am (CST)Where[https://jpmchase.zoom.us/j/96369971376](https://jpmchase.zoom.us/j/96369971376)WhoInterdonato, Brian M\*_No earlier events_10amInterview for SR Lead Software Engineer - JPMorgan Chase_No later events_AgendaThu Jan 23, 2025HI Qiong, Here is the info for your Zoom meeting with Ramon Solis and Wayne MFarlane.

Did you know that JavaScript is the most popular programming language used by 63.3% of software engineers? This popularity is due to its versatility, rich ecosystem, high performance, and active community. As a result, hiring skilled JavaScript developers is crucial for building dynamic, scalable applications that meet modern user expectations and keep you ahead in a competitive market.

This guide walks you through hiring JavaScript developers, from defining your project needs to finding top developers, setting budgets, and avoiding common pitfalls.

What does a JavaScript developer do?

From writing efficient code to improving user experiences and ensuring compatibility across browsers, JavaScript developers are responsible for creating dynamic and responsive digital products. Depending on their expertise, they typically specialize in front-end, back-end, or full-stack development. Following are the core responsibilities of JavaScript developers.

Core responsibilities

A JavaScript developer's primary role is to design, build, and maintain websites and web apps using JavaScript. This programming language is flexible and widely used. Key tasks include:

  • Writing clear code: Writing clear, efficient, and easy-to-update JavaScript code is the key responsibility of JavaScript developers. They use naming conventions, modular code structures, and comments to make code scalable and future-proof, reducing the risk of errors when modifications are needed.
  • Adding interactive features: JavaScript developers add interactive features such as clickable elements, pop-ups, and animations. These features allow website visitors to interact with the back end, making the site more engaging and responsive to user actions.
  • Connecting JavaScript with tools: JavaScript works with HTML and CSS to create rich user interfaces. JavaScript developers connect JavaScript with these two technologies to make websites look pleasant. They also use APIs to allow web applications to fetch and display real-time data, further expanding their functionality.
  • Improving website performance: JavaScript developers are also responsible for optimizing JavaScript to improve a website’s performance. This includes faster load times, smoother interactions, and compatibility across different browsers and devices for a consistent user experience, requiring thorough testing and adjustments for each platform.
  • Fixing and solving issues: Debugging and troubleshooting are crucial skills for any JavaScript developer. This involves using tools like browser consoles, testing frameworks, and error logs to identify and resolve problems. A proactive approach to testing code can prevent issues before they reach production, ensuring a more stable and reliable application.
  • Collaborating with technical and non-technical teams: JavaScript development often involves working closely with designers, project managers, and other developers to ensure that functionality aligns with design and project goals. JavaScript developers have good communication and collaboration skills to provide a cohesive final product that meets user expectations and project deadlines.

Types of JavaScript developers you can hire

JavaScript developers generally fall into three categories based on their skills:

Front-end developer

Front-end developers are responsible for creating the parts of a website or app that users interact with directly. They use JavaScript frameworks like React, Vue.js, and Angular to build user-friendly interfaces and manipulate the Document Object Model (DOM) to create dynamic, interactive experiences. They craft responsive designs that adapt to different screen sizes, ensuring a seamless experience on mobile devices, tablets, and desktops. These developers focus on improving user experiences (UX) by incorporating interactive elements like animations, sliders, and buttons. They also ensure that the front end integrates smoothly with the back end, working closely with back-end developers to optimize data flow and performance. In addition to technical skills, a strong sense of design and an understanding of user behavior are crucial for front-end developers.

Back-end developer

Back-end developers focus on the back-end (behind the scenes) aspects of app and web development projects. They work with tools and JavaScript frameworks like Node.js and Express.js to manage server-side logic, ensuring the functionality that supports the front end. Their responsibilities include building APIs (Application Programming Interfaces), which allow the front end to communicate with databases and other web services. Back-end developers handle tasks like data processing, storage, and retrieval, often connecting to databases such as MySQL, MongoDB, or PostgreSQL. They also set up security features like authentication and encryption to protect sensitive user data. A crucial part of their job is ensuring that the app can scale securely as the number of users grows, maintaining performance under increased load. Their role is foundational to a web or mobile application's stability, speed, and security.

Full-stack developer (MEAN, MERN stack)

Full-stack developers manage both front-end and back-end tasks. They work across the entire web technology stack like MEAN (MongoDB, Express.js, Angular, Node.js) or MERN (MongoDB, Express.js, React, Node.js) to handle everything from designing user interfaces to writing server-side code. Their ability to work across the entire web development process allows them to oversee complete projects. Full-stack developers often manage databases, ensuring data flows smoothly between the user interface and the server. They are skilled in troubleshooting issues across the application, making them valuable for maintaining and improving complex projects. Full-stack developers are also well-suited for startups or smaller teams, where flexibility and the ability to switch between different tasks are essential.

Why hire JavaScript developers?

From e-commerce sites to mobile apps, JavaScript programmers play a key role in building engaging, easy-to-use products that meet a wide range of business needs. Following are the key benefits JavaScript developers bring to your business.

Business benefits of hiring javascript developers

JavaScript developers bring key skills that help businesses grow and improve customer experiences. They can create apps across web browsers, mobile devices, and desktops. This versatility lets companies reach more people and meet various user needs.

JavaScript enables interactive, dynamic user interfaces. This improves user experience with features like smooth animations, responsive designs, real-time updates, and data visualizations. Developers use JavaScript to build applications that are engaging and easy to navigate, keeping users satisfied.

Use cases for various projects

JavaScript developers are crucial for a variety of projects, including:

  • E-commerce websites: Develop features like secure payments, shopping carts, and personalized recommendations.
  • Single page applications (SPAs): Build fast, responsive apps that load on a single web page for a smooth, app-like experience.
  • Mobile apps: Use frameworks like React Native to create apps that work on iOS and Android.
  • Real-time apps: Use WebSockets and Node.js to build real-time apps for chatting, collaboration, and live data streaming.
  • Internal tools and dashboards: Create custom tools, dashboards, and data platforms to improve productivity and operations.

Rising demand for JavaScript developers

Demand for JavaScript developers is growing as businesses prioritize excellent digital experiences. New frameworks like React, Angular, and Vue.js have increased the need for developers skilled in these tools.

The rise of full-stack development, where developers handle both front-end and back-end tasks, has further driven demand for JavaScript programmers who can manage complete projects.

How to hire a JavaScript developer

A structured approach to hiring javascript developers ensures you find the best fit for your project. The following steps will help you hire a JavaScript developer that meets your business needs.

Step 1: Define your project needs

Before searching for a JavaScript developer, clarify your project's goals. List the features, functions, and expected results. Determine if you need a front-end, back-end, or full-stack developer based on your project. Also, consider the timeline, budget, and whether you need a junior, mid-level, or senior developer.

Step 2: Write your job description

Create a comprehensive job description outlining the role and responsibilities. Include details about the project, required skills, and any tools or frameworks the software developer should know. Post the job on boards, freelancing sites, and developer communities to attract more candidates.

Step 3: Pre-screen candidates

Review each candidate’s resume, portfolio, and code samples as applications come in. Look for relevant experience, proficiency in web technologies, and a good understanding of JavaScript fundamentals. Use screening interviews or coding tests to assess their technical and problem-solving skills.

Step 4: Conduct interviews

Set up an interview process to evaluate top candidates' technical knowledge, communication skills, and fit with your team. Prepare coding challenges or real-world problems to test their abilities. Ask specific interview questions about their experience with JavaScript frameworks or tools relevant to your project.

Step 5: Make the hire

After evaluating all candidates, choose the one that best fits your needs. Agree on terms, including pay, benefits (if applicable), and the project timeline. Be sure to outline the project scope and expectations in a contract. Once hired, provide the tools and support for a smooth start.

Key skills to look for in JavaScript developers

The right candidate should have a solid grasp of JavaScript fundamentals and relevant tools and be able to communicate well and work well in a team. Understanding the key hard and soft skills to look for ensures that you find a developer who can contribute to your project’s success and collaborate easily with other stakeholders.

Technical skills

The technical knowledge of each JavaScript developer varies based on their expertise, but the essential technical skills include:

  • Core JavaScript concepts: This includes understanding variables, functions, and objects, including traditional and arrow functions, and knowing how to create and invoke them efficiently.
  • ES6+ features: Familiarity with ES6+ features is essential in modern JavaScript development. These newer additions to the language make the code more concise, easier to read, and more efficient.
  • JavaScript frameworks: Skilled developers are familiar with JavaScript frameworks like React, Angular, and Express, depending on their area of expertise.
  • Version control: Version control is critical to modern software development, and familiarity with tools like Git and GitHub is non-negotiable.
  • Testing tools: To ensure code quality and reliability, hiring JavaScript developers familiar with testing tools like Jest or Mocha is essential.

Soft skills

In addition to technical expertise, soft skills are essential for JavaScript developers. The following are the must-have soft skills for JavaScript developers:

  • Communication: Communication skills are essential because developers often need to explain complex technical issues in a way that non-technical team members, like designers and project managers, can understand. Clear communication ensures everyone is aligned on project goals, timelines, and expectations.
  • Problem-solving: Problem-solving skills are crucial for JavaScript developers, as they often encounter technical challenges and roadblocks during development. Whether it's debugging a complex piece of code, optimizing the performance of an application, or finding a workaround for an unforeseen issue, developers need to think creatively and quickly.
  • Adaptability: JavaScript developers experienced with Agile methodologies like Scrum or Kanban have an advantage. Agile methods emphasize adaptability and iterative development, allowing teams to respond quickly to changes in project requirements or user feedback. Developers who understand Agile are used to working in short development cycles (often called sprints) and can deliver incremental improvements to a product, which leads to more efficient project management.
  • Time management and project ownership: Time management is another essential soft skill for JavaScript developers, especially when juggling multiple tasks or working on complex, long-term projects. In addition, project ownership is an important quality. The best JavaScript developers take responsibility for their work and feel accountable for the final product. They proactively identify issues, seek improvements, and ensure their code is maintainable and scalable, contributing to more efficient and successful projects.

How to write an effective JavaScript developer job description

A clear job description is the key to attracting the right JavaScript developers. The following guidelines will help you write a job post outlining the specific role, required skills, and project details, ensuring candidates understand your expectations.

Guidelines for writing a JavaScript developer job description

To attract the right candidates, keep your job description clear and direct. Follow these steps:

  1. Job title and overview: Start with a specific job title, like "Front-end JavaScript Developer" or "Full-stack JavaScript Developer." Then, provide a brief overview of the main responsibilities and the types of projects the developer will work on.
  2. Define the scope of work: Clearly outline what the developer will do, such as building and maintaining web applications, designing user interfaces, integrating APIs, or working with databases and back-end systems.

Questions to ask JavaScript developers before hiring

Asking the right questions is important to assess a JavaScript developer's technical knowledge and problem-solving abilities. The following questions will help you gauge a candidate's understanding of key JavaScript concepts and best practices, ensuring they have the skills needed for your project.

1. Explain the difference between let, const, and var in JavaScript. When would you use each?

This question tests the candidate’s understanding of JavaScript variables. A good answer will explain block scoping, hoisting, and when to use let, const, or var.

2. What is the difference between an array and an object in JavaScript? How would you loop through each?

This checks the candidate’s knowledge of JavaScript data structures. They should explain how arrays and objects differ and describe looping methods like for, forEach, map, or Object.keys().

3. Explain the concept of closures in JavaScript and provide an example of when you'd use them.

Closures are a key concept in JavaScript. A solid answer will define closures and give an example, like using them for data privacy, event handlers, or currying.

4. How would you build a simple React component that fetches data from an API and displays it?

For front-end roles, this question checks React and API handling skills. They should explain how to manage state, make API calls with fetch or Axios, and handle React lifecycle methods.

5. What is the difference between imperative and declarative programming? Which style does React use, and why?

This question checks their understanding of programming styles. A good answer compares imperative (step-by-step) and declarative (defining outcomes) approaches, explaining why React uses declarative programming for building UIs.

6. How would you improve the performance of a React app? Share specific methods or tools you would use.

Optimizing performance is critical. The candidate should mention techniques like code splitting, memoization, virtualized lists, and tools such as React.memo, useMemo, and useCallback.

7. Explain the difference between Promises and Async/Await in JavaScript. When would you use each?

This checks their grasp of asynchronous programming. A good response explains how Promises and Async/Await work, when to use them, and their role in JavaScript's event loop.

8. How would you write unit tests for a React component? Explain the steps and tools you’d use.

Unit testing is important for code quality. They should mention tools like Jest or Enzyme and explain how to test React components by simulating user interactions and checking expected outcomes.

9. What are higher-order functions in JavaScript? Give an example of when you'd use one.

This tests their knowledge of functional programming. A good answer will define higher-order functions, highlight their benefits (e.g., code reuse), and provide examples like map, filter, or reduce.

10. How would you handle form validation in a React app? Discuss different methods and tools.

This question checks their approach to form validation in React. They should talk about client-side and server-side validation, and tools like Formik or React Hook Form, focusing on user experience.

How much does it cost to hire JavaScript developers?

Asking the right questions during the interview helps assess a JavaScript developer's technical skills and problem-solving abilities, ensuring they fit your project. The following questions will help evaluate your candidate’s expertise.

Freelance vs. full-time developers

Hiring freelance JavaScript developers can be more affordable in the short term compared to full-time employees. With freelancers, you only pay for the work done or the project length, avoiding extra costs like benefits, payroll taxes, and office space.

However, hiring a full-time JavaScript developer might be more cost-effective for long-term or ongoing projects. Full-time developers focus solely on your project, integrate into your team, and align better with your company’s culture, leading to greater productivity and better outcomes.

Factors that affect cost

Several factors influence the cost of hiring JavaScript developers, including:

  • Experience level: Junior developers typically charge $15 to $50 per hour, mid-level developers $50 to $100 per hour, and senior developers with extensive experience $100 to $150 per hour or more.
  • Location: Rates vary based on the developer's location. Developers in higher-cost regions like the U.S. or Western Europe usually charge more than those in lower-cost areas such as Eastern Europe, Asia, or South America.
  • Project type and complexity: Simple tasks like fixing bugs or basic scripting are less expensive. More complex projects, such as building web apps or developing software, require more time and skill and cost more.

Average rates for hiring JavaScript developers

Here are typical rates based on experience and project type:

Rates by experience:

  • Junior: $15-$50/hour
  • Mid-level: $50-$100/hour
  • Senior: $100-$150/hour

Rates by task complexity:

  • Software development: $133 per job (average)
  • Interactive web applications: $92 per job (average)
  • Scripting: $38 per job (average)
  • Software bug fixes: $49 per job (average)
  • Website bug fixes: $36 per job (average)
  • Custom websites: $10 per job (average)

These are general estimates, and actual rates may vary based on the project's specifics, the developer's skills, and other factors mentioned above.

Where to find and hire top JavaScript developers?

Depending on your needs and budget, there are several ways to hire top JavaScript developers. The following are some of the best platforms to consider when hiring JavaScript developers.

Best platforms to find JavaScript developers

Several platforms can help you find skilled JavaScript developers. However, each platform has pros and cons, so it's important to understand their offerings before committing to one. Some of the best platforms for hiring Javascript developers include:

  • Arc: Arc provides an extensive pool of vetted remote JavaScript developers within your budget. All developers on Arc go through a comprehensive vetting process to ensure top-quality talent.
  • Upwork: JavaScript developers on Upwork have hourly rates as low as $10, but you’ll need to carefully vet candidates to ensure they meet your project requirements. Therefore, hiring takes longer and can lead to poor-quality hires if the vetting process is insufficient.
  • Toptal: Toptal has a strict vetting process and accepts only the top 3% of applicants. However, Toptal is expensive and might not be suitable for small and medium-sized businesses.
  • JavaScript communities: JavaScript communities like Stack Overflow and Dev.to offer a great way to connect with passionate developers, review their contributions, and engage with them directly. However, finding the right match may take time, as these platforms aren't primarily designed for hiring, and you'll need to assess skills independently.

Agency vs. freelance vs. in-house hiring

You can hire JavaScript developers through an agency, work with freelancers, or build your in-house team. Each option has its pros and cons:

Agency hiring:

  • Pros: Agencies manage the hiring process and often have pre-vetted developers.
  • Cons: Higher fees and less control over the process.

Freelance hiring:

  • Pros: Freelancers offer flexibility for short-term or specific projects, often cheaper than agencies or full-time hires.
  • Cons: You’ll need to manage the hiring and project yourself, and communication can be challenging with remote freelancers.

In-house hiring:

  • Pros: You have full control over hiring and project management. Hiring a dedicated developer helps you achieve long-term goals, providing consistency and deeper integration with your team and projects.
  • Cons: It’s more expensive, with costs for salaries, benefits, and office space. Finding the right candidate can also take longer.

The best option depends on your project size, budget, and plans. Freelancers or agencies may be better for short-term projects, while in-house hiring works best for long-term or larger projects.

How long does it take to hire a JavaScript developer?

Whether you're hiring a freelancer for a quick task or a full-time developer for a long-term project, the timeline for both hiring and project completion will depend on your needs, the complexity of the project, and the developer's experience. Here's a breakdown of typical timelines for hiring and completing JavaScript projects.

Average time to hire freelancers vs. full-time developers

Hiring freelance JavaScript developers is usually quicker than hiring full-time employees. You can find pre-vetted freelancers on platforms like Arc in seconds with the help of its AI recruiter, HireAI. On Fiverr or Upwork, it typically takes 3 days to find and review candidates.

Hiring a full-time JavaScript developer takes longer. The process, from posting the job and reviewing resumes to interviews and final decisions, typically takes 2-4 weeks for most companies.

Project timelines

The time required to complete a JavaScript project depends on its size, complexity, and the developer’s experience. Here are some estimates for common projects:

Web applications:

  • Simple web app: 2-4 weeks
  • Medium complexity web app: 1-3 months
  • Complex web app with advanced features: 3-6 months

Bug fixes and maintenance:

  • Minor bug fixes: A few hours to a few days
  • Major bug fixes or code updates: 1-2 weeks

Mobile app development:

  • Basic mobile app: 1-2 months
  • Complex mobile app with advanced features: 3-6 months

Custom website development:

  • Basic website: 2-4 weeks
  • E-commerce or content-heavy website: 2-4 months

These are general estimates. Actual timelines can vary depending on the project's specifics, the developer's availability, and any unexpected challenges during development.

Common pitfalls to avoid when hiring JavaScript developers

A thorough, clear, and balanced approach to hiring ensures a smooth hiring process and successful project outcomes. Below are the common mistakes to watch out for when hiring JavaScript developers.

Hiring without proper screening

A common mistake is skipping thorough screening when hiring JavaScript developers. Reviewing resumes and portfolios alone won’t reveal a candidate’s actual abilities. Including technical assessments, coding challenges, and detailed interviews is crucial to hiring someone with the right skills for your project. You risk hiring an unqualified developer without proper vetting, leading to poor-quality work, missed deadlines, and wasted resources.

Miscommunication on project scope

Clear communication is essential, especially regarding project scope. Misunderstandings about goals, deliverables, or deadlines can cause delays, extra work, and frustration. Before hiring, document the project’s objectives, features, and desired outcomes. Ensure you and the developer are on the same page and have aligned expectations.

Focusing only on cost

While staying within budget is important, focusing solely on cost can lead to issues. Choosing developers based only on a lower rate may mean compromising on experience or skills, resulting in subpar work or technical issues. This can lead to costly rework later. Instead, balance cost and quality by carefully reviewing portfolios and considering experience and track record.

Key takeaways to hire the right JavaScript developer

Hiring a good JavaScript developer is crucial for businesses building dynamic, mobile, and scalable solutions. However, attracting the best JavaScript developer requires a clear project scope and a detailed job description.

Look for a mix of technical and soft skills and use coding challenges and real-world exercises during the interview process. The cost of hiring JavaScript developers varies with experience, location, and project complexity. However, a clear understanding of your requirements and deliverables will help you attract expert JavaScript developers that align with your goals.

Once you understand your requirements, begin your search on platforms like Arc that provide access to in-budget yet vetted remote developers and help you avoid common mistakes. With these guidelines, you can hire remote JavaScript developers who understand your values and deliver scalable applications that meet customer expectations.
