Interview Prompt

Each row of `deploy_logs` is one deploy, and the release team is scoring authors on their recent deploy record. Give each author their average deploy duration in seconds, a score of (100 minus that average) times their number of deploys, and a standing where 1 is the strongest score.

Summary

Not all deployers are equally reliable.

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
