Interview Prompt

During an active incident, the incident commander needs full details for the service that has received the most alerts where severity contains the word 'critical'. Return all columns for every alert belonging to that service, ordered by fired_at.

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
