Frequently Asked QuestionsAbout Senior App Developer Hiring

A Senior App Developer focuses more on hands-on development while providing technical guidance, whereas a Technical Lead primarily manages team direction and technical strategy with less direct coding.

Use whiteboard sessions focusing on real-world architecture challenges and ask candidates to explain their decision-making process for previous complex projects they've led.

For most organizations, strong mobile platform expertise is more crucial as it's harder to find and directly impacts product quality. Full-stack capabilities can be supplemented by specialized backend developers.

Watch for candidates who can't explain architectural decisions in previous projects, show resistance to code reviews, or lack experience mentoring junior developers.

While 5+ years is typical, focus on the quality of experience rather than quantity. Look for candidates who have led significant projects and can demonstrate strong technical decision-making abilities.
