Interview Prompt

We're profiling read-only API users: people who have only ever called the API with GET and never any other method. For each endpoint, count these read-only users, and return the endpoint or endpoints with the highest count.

Summary

Some users only ever read, never write. Find where the read-only crowd gathers.

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
