Interview Prompt

We're mapping how review attention spread across each codebase year over year. For every repo in a given calendar year, find how many different people reviewed its code, reporting the year as a whole number.

Summary

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

  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
