This sounds like a standard 'tell me about yourself' project question until they start pulling threads.
Choose a project that demonstrates technical depth, cross-functional collaboration, and measurable impact, ideally with a clear trade-off. Structure your answer using a narrative arc: context, problem, your role, key decisions, results, and reflection. Be specific about your contributions versus the team's, and quantify outcomes to show impact.
Pro tip: Focus on the 'why' behind your decisions and trade-offs, not just what you did. Show self-awareness by discussing what you'd change and how you've applied those lessons since.
Briefly describe the project, its goals, and the specific problem it solved. Highlight why it mattered to the business or users.
Clearly state your specific responsibilities and how you collaborated with others. Distinguish your individual contributions from the team's.
Walk through 1-2 critical technical decisions, the alternatives considered, and the trade-offs (e.g., performance vs. maintainability). Explain your reasoning.
Share measurable results (e.g., latency reduction, cost savings, user growth) and any qualitative impact (e.g., improved team processes).
Discuss one thing you'd do differently and what you learned. Show how this reflection has influenced your subsequent work.
