Your question is Learning from a Failure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Give me an example of a project where you failed, what happened, and what you learned from it. Choose a specific project where your decisions or actions materially contributed to an unfavorable outcome. Explain the stakes, your responsibility, how you responded, the measurable result, and the concrete change you made afterward. Focus on ownership rather than assigning blame.
