Interview Prompt
We're profiling read-only API users: people who have only ever called the API with GET and never any other method. Count these users for each endpoint, 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
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
