Use STAR: "In my 3rd year, I led a team for a college hackathon. I took on too many features and we couldn't complete the project. I learned to scope MVPs and prioritize ruthlessly. In the next hackathon, I defined a clear MVP first, and we won 2nd place."

By Monday, I submitted my first PR. Within 2 weeks, I was contributing independently. Key: I focused on learning by doing, not just reading docs."

"I believe in data-driven decisions. When my manager suggested using REST for a real-time feature, I prepared a comparison showing WebSocket reduced latency by 80%.

"I use the Eisenhower Matrix: Urgent+Important (do first), Important+Not Urgent (schedule), Urgent+Not Important (delegate/automate), Neither (drop). I also communicate proactively — if I can't meet a deadline, I flag it early with a revised estimate and a plan."
