Welcome to your interview.
The question is on your right: Optimizing SQL for Terabytes. 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.
How do you ensure your SQL queries are optimized for performance when dealing with terabytes of data?
