Interview Prompt

During an incident review, the on-call team needs the oldest unresolved alert for each service. Show the service name, alert ID, severity, status, and the time the alert was fired, by service name.

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
