Welcome to your interview.
The question is on your right: Materialized vs Standard Views. 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.
Can you explain the performance implications of using materialized views versus standard views in your current warehouse?
