Your question is Preventing Suspicious Activity. 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 when you identified suspicious activity and prevented further exposure. Briefly explain what raised your concern, how you validated the issue, what actions you took, and the outcome. Focus on your judgment, prioritization, communication, and ownership rather than confidential details.
