Interview Prompt

Our on-call team reviews reliability per service from `alert_events`, where each alert records the service that fired it and a resolution timestamp. Show how many of each service's alerts are resolved versus still unresolved, as two separate columns.

Summary

Resolved versus open. By severity.

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
