The reliability team wants each service's latency sitting next to the baseline for its region. For every health check, return the service name, region, its latency, and the average latency across all services in that same region.
Summary
Each service versus its region's average.
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
