Walk me through a project you led end-to-end. What was your role, what shipped, and what didn't go to plan?

Imagine you're building a treehouse with friends. You're the one who decides where to put the ladder, who nails the boards, and what to do when the wood runs out. This question is like asking you to tell the story of that treehouse—what you built, how you led, and what went wrong—so they can see if you're a leader who can handle surprises.
