Interview Prompt

We're profiling who was shipping code in each repo's scrappy early days, before it ever logged a successful CI build. For each of those authors, report their average lines added and average lines removed per commit, biggest contributions first.

Summary

Every repo has a scrappy stretch before its first green build. See who was shipping then, and how big their changes were.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
