Interview Prompt

We're building a single per-user report that combines session engagement with transaction revenue. For each user, show their name, their session count, and their total transaction amount, and keep every user in the report even if they never logged a session or a transaction.

Summary

The quietest accounts still belong in the numbers.

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
