Your question is Finding and Fixing Critical Flaws. 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).
Describe a time you identified a critical flaw in an existing system and how you navigated the fix.
Explain how you recognized the flaw, assessed its impact, prioritized the response, and worked with others to address it. Include how you handled disagreement or uncertainty, communicated risk, protected users or business operations, and verified that the fix worked. Strong answers use a specific example, distinguish immediate mitigation from the durable solution, acknowledge the candidate’s own role, and conclude with measurable results and a lesson learned.
