Interview Prompt
An analyst suspects the catalog only looks diverse and that a handful of products carry most of the sales recorded in `transactions`, where a product's revenue is its total amount across every sale. Build her a leaderboard of the top 10, each product shown with its name from `products`, its total, and its position on the board.
Summary
Total sales tell the real story. Surface the products that carry the catalog.
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
