Welcome to your interview.
The question is on your right: Evaluate a Churn Model. 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 reviewing a binary classification model that predicts which customers are likely to churn. The team wants a clear framework for judging whether the model is good enough to use in retention campaigns.
What metrics would you use to evaluate a churn model?
