Welcome to your interview.
The question is on your right: Model Validation Approach. 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.
Explain a statistical or machine learning model you have used recently at Point Digital Finance. How did you validate its performance?
