Welcome to your interview for the Customer Success Engineer role at ScienceLogic.

The question is on your right: Optimize Slow SQL Query. 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. You have three graded attempts to score 7/10 or better.

Only Submit answer is graded - discussion is free practice.

Problem

Walk me through how you would optimize a slow-running SQL query on a database containing millions of system performance logs.
