Interview Prompt

Our platform team wants to see which endpoints attract the most power users. Someone is a power user of an endpoint when the standard API methods make up at least half of their calls to that endpoint. List every endpoint with its power-user count, most first.

Summary

Power users have a favorite endpoint.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
