Your question is Testing Ambiguous Safety-Critical Behavior. 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 you had to create a test strategy for a safety-critical or edge-case behavior where requirements were incomplete or still evolving. Walk me through how you defined scope, aligned with cross-functional partners, and decided what to test first when the scenario involved rare but high-risk obstacles or events.
