Welcome to your interview.
The question is on your right: Monitor and Improve Model Performance. 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 are responsible for a model that is already in production, and the team wants a clear way to watch its performance over time. The main concern is knowing when the model is drifting, when the threshold is no longer right, and when a retrain or rollback is needed.
How would you monitor model performance and implement improvements as necessary?
