Interview Prompt

The on-call team's job report keeps breaking on `batch_jobs` rows that violate its two rules: every job should have an `ended` time by now, and no job should end before it `started`. List the jobs that break either rule with their `job_id`, `job_name` and runtime in minutes.

Summary

Promised by noon. Delivered at midnight.

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
