Tell me about a project you're proud of. What was your contribution and what did you learn?

Interviewers ask this question to understand three things at once: what you've actually built, how you think about your own work, and whether you can communicate clearly. The best answers are specific (a real project, not a vague description), personal (your role, not just 'we did everything'), and reflective (what you learned, not just what you shipped). Use the STAR structure to stay organised: Situation → Task → Action → Result.
