Developers who struggle to communicate effectively can create confusion, misunderstandings, and delays. During the interview process, assess how well they explain technical concepts, handle feedback, and collaborate with others. Developers with good communication skills are more likely to update you on progress, proactively solve problems, and work smoothly within a team.
Not testing with a trial project
Hiring an app developer for a long-term project without first seeing how they perform can be risky. A small trial project is an excellent way to evaluate their coding abilities, problem-solving skills, and ability to meet deadlines. It also gives you a sense of how well they work within your team and whether they understand your business needs. A trial project can reveal potential red flags early, saving you from costly mistakes.
Rushing the hiring process
Hiring too quickly can lead to regrettable decisions. In the rush to fill a position, you might overlook red flags or skip important steps like portfolio reviews, reference checks, or detailed interviews.

If you notice patterns of missed deadlines early, this could indicate future problems with larger, more complex deliverables. Time management is essential for keeping your project on schedule and within budget.
Ignoring large upfront payments
It could be a warning sign if a mobile app development agency asks for a large upfront payment. While it’s normal for mobile app development companies to require a deposit, demanding a significant portion of the total cost before starting work may signal potential risks. To protect yourself, research the agency, read client reviews, and request a detailed contract before making any financial commitment.
Ignoring the lack of transparency
Ignoring a lack of transparency can be a significant red flag when hiring developers. Fraudulent companies or developers often withhold clear communication and detailed project plans, making it hard to assess their credibility. A lack of transparency in timelines, deliverables, or payment structures should raise concerns. Reputable developers provide a clear project roadmap with timelines, milestones, and a detailed cost breakdown. If a mobile app development company or developer is vague or avoids answering questions, it could signal incompetence, hidden fees, or even a potential scam.
"One thing I’ve learned when hiring mobile developers is not to over-prioritize familiarity with tools at the expense of problem-solving skills. I always ask how they’ve debugged tricky issues or improved app performance because those answers reveal so much more about their ability." — Jeff Lam, Head of Talent & Global Partnership at Arc
