Welcome to your interview.
The question is on your right: WHERE vs HAVING vs GROUP BY. 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 the differences between GROUP BY, HAVING, and WHERE clauses, and write a query that utilizes all three to filter aggregated data.
