Interview Prompt

A CI platform's reliability team wants to see how build activity breaks down by what kicked each build off. For each trigger type, show how many builds it produced and their average duration in seconds.

Summary

Every build has a cause. Tally the work behind each one.

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
