Interview Prompt

Our users table records each account's status and signup date. For each account status, return the user who signed up most recently, with their identifying details.

Summary

Carbon copies clutter the table. Only the latest matters.

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
