Your question is Stepping Beyond Scope Under Pressure. 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 went beyond your defined scope of work to solve a critical problem. What made the issue important, how did you decide it was worth stepping in, and what was the outcome?
