Interview Prompt

The platform catalog needs a service taxonomy. Classify each service: 'api_service' if the name contains 'api', 'cache_service' if it contains 'cache' or 'redis', 'database' if it contains 'db' or 'postgres', and 'other' for everything else. Each service should appear only once. Show the service name and its category, limited to the first 100 results.

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
