Interview Prompt

After a string of rollbacks, leadership asked how much deployment capacity each service loses to failures. For each service, show what percentage of its deployments failed and what percentage of its total deployment time was consumed by those failures.

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
