Welcome to your interview.
The question is on your right: Heuristics vs Machine Learning. 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.
When is it appropriate to use a heuristic-based solution versus a machine learning model?
