Interview Prompt
We run an online education marketplace. Two types of users (students and instructors) can subscribe to different plan tiers. Students pay for access; instructors pay for listing and promotion features. Multiple payment methods are supported. Finance needs month-over-month growth reports and outstanding balance tracking. Design the data model, then write the SQL for MoM subscription growth.
