Your question is Code Review Vulnerability Discovery. 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).
Walk me through a time you identified a security vulnerability in a code review.
Explain the technical issue, how you assessed its severity, and how you communicated it to the author or team. Describe any disagreement, delivery pressure, or ambiguity you faced, the actions you took to drive remediation, and the final outcome. The interviewer is evaluating security judgment, attention to detail, influence without authority, and ownership. A strong response should use one specific example, explain the vulnerability without exposing sensitive information, distinguish impact from theoretical risk, and quantify the remediation result where possible.
