Your question is Diagnose Production Model Underperformance. 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).
You've shipped a model that looked strong in validation, but it is underperforming in production. The team wants to know why the gap appeared after launch and what you would do next.
Tell me about a time your model underperformed in production. How did you diagnose and fix it?
