Your question is Handling Your Biggest Mistake. 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).
What was your biggest mistake on the job and how did you handle it? Choose one specific professional example rather than describing a minor error or a hypothetical situation. Explain the stakes, your personal responsibility, the actions you took to contain and correct the mistake, and what changed afterward. Be candid about the outcome and the lesson you carried forward.
