Interview Prompt

During an incident postmortem, the on-call engineer needs to know which regions produce the most critical alerts. Use service health checks to map each service to its region, count critical-severity alerts per region, and return the top 5 regions by alert volume.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
