Interview Prompt

The SRE team considers a service stable only if it recorded healthy checks across multiple quarters. Find services that had at least one healthy check (case-insensitive) in at least two separate quarters of 2026.

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
