Interview Prompt
The incident response team only trusts alert data from services that also show up in the health check system. For those services, look at each service-and-severity combination that fired more than once in 2026, and report the average number of alerts per combination for each severity level.
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 your sql solution with real code execution
