Welcome to your interview.
The question is on your right: Owning a Security Vulnerability Discovery. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Tell me about a time you identified a meaningful security vulnerability in a system or process. How did you validate the risk, communicate it to the right stakeholders, and drive remediation through to closure?
