The eng director wants to know which repositories are absorbing the most new code. From `repo_commits`, find the repos whose total lines added beat the average repo, with that total and how many commits produced it.
Summary
Some repos never sleep.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
