Interview Prompt
During an incident review, the on-call team needs the oldest unresolved alert for each service. For each service, return the service name, alert ID, severity, status, and the time the alert fired.
Summary
Every service has one alarm that was never silenced. Find the one that has been screaming the longest.
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
