Interview Prompt

Each row of `repo_commits` is one commit, with its author, its timestamp and the lines it added. Across 2026, which author most often landed the month's biggest commit, and how many times?

Summary

In a sea of commits, only a few wear the crown.

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write and run your SQL against a real database
4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
