Your question is Recovering a Failed Customer Deployment. 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 a critical technical deployment failed or fell short of a customer's expectations. How did you communicate the issue, manage the relationship, and drive the resolution? If relevant, include how you handled escalation, root cause, and the steps you took to rebuild trust afterward.
