Interview Prompt

The release manager wants to see build volume broken down by who triggered the build and which branch it ran on. Show each trigger-branch combination with its build count, ordered alphabetically by trigger and branch, then by count descending.

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
