Your question is Pivoting a Failing Research Project. 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 project you were leading was not producing the expected results. How did you diagnose what was going wrong, decide whether to pivot, and align others around the new direction? Walk me through the outcome.
