Welcome to your interview.
The question is on your right: Clicks Within Five Minutes. 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.
Given a table of ad impressions and a table of user clicks, write a query to identify users who clicked on an ad within 5 minutes of viewing it for Lg Ad Solutions.
