Welcome to your interview.
The question is on your right: Optimizing a Model With Data. 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.
If you were asked to optimize the model, what data would you need and how would you optimize it?
