Your question is Fixing a Critical System Flaw. 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 identified a critical flaw in a system and how you resolved it. Focus on how you recognized the severity, validated the issue, prioritized the response, and worked with others to implement a durable fix. Explain the outcome, including measurable impact where possible, and what you learned about preventing similar failures.
