What Is a Project You're Most Proud Of?

Question

Walk me through the project you are most proud of — your specific contribution, the hardest technical problem, and the impact.

What the interviewer looks for

• Personal contribution vs team
• Technical depth you can defend
• Impact measured in user/business terms (Meta loves metrics)

Tips

Meta behavioral rounds map to signals like 'drives results' and 'embraces ambiguity'. Have numbers ready and own your role explicitly.
