Your question is Owning a Meaningful 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).
Tell me about a time you failed on an important project or decision. What was the situation, what did you do, how did you handle the consequences, and what did you learn that changed how you work today?
