Welcome to your interview.
The question is on your right: SQL Window Functions for Top N. 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.
What are window functions in SQL, and how would you use them to find the top three highest-paid employees in each department?
