Interview Prompt

We're mapping how review attention spread across each codebase year over year. For every repo in a given year, find how many different people reviewed its code, and surface the pairings with the most reviewers first.

Summary

Every codebase draws its own circle of watchers. Count who shows up.

  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
