Interview Prompt
An analyst noticed the bulk-checkout invite list was counting refunds and zero-value adjustments in `transactions` as purchases, which pushed the wrong buyers over the bar. Rebuild it: every user in `users` with more than twelve purchases, showing their username, purchase count and total spent, biggest spenders first.
Summary
Power buyers. Big carts.
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
