Welcome to your interview.
The question is on your right: Diagnose Production Model Underperformance. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
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?
