Your question is Handling a Critical Defect. 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 defect that would have impacted the user experience; how did you handle it?
Explain how you assessed the severity, communicated the risk, and decided whether to block or adjust the release. We are looking for a specific example that shows ownership, practical prioritization, collaboration with engineering and product, and attention to customer impact. A strong response should use STAR, distinguish the immediate containment from the permanent fix, and explain how you verified the outcome and improved the process afterward.
