Interview Prompt

The API product team is sizing per-endpoint user reach for June 2026 to inform deprecation decisions. For each endpoint, how many unique users called it that month?

Summary

One endpoint, many users. Which ones showed up?

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
