Your question is Recovering From a Communication Breakdown. 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 an interviewer, stakeholder, or cross-functional partner stopped responding or missed a critical meeting, and communication broke down. How did you handle it, how did you decide whether to wait, follow up, or escalate, and what was the outcome?
