Interview Prompt

The engineering lead needs a per-repo build health snapshot before freezing deploys: how many builds succeeded, how many failed, and the average build duration.

Summary

Green versus red, repo by repo.

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
