Welcome to your interview.
The question is on your right: Monitor Model Performance Over Time. 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 deployed a model and it looked strong at launch, but the data it sees in production keeps changing. The team wants a plan for watching performance over time and catching drift before it causes business damage.
How would you continuously monitor a deployed model and maintain its performance over time?
