Welcome to your interview.
The question is on your right: Trending Subreddits in 24 Hours. 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 user upvotes and downvotes, write a query to find the top trending subreddits based on activity velocity over the last 24 hours on Reddit.
