Interview Prompt
An on-call lead only trusts alerts from services that also report into `svc_health`. She wants each severity's average alert count across the service-severity pairs in `alert_events` that fired more than once.
Summary
The alert volume varies. So does what it means.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
