Interview Prompt
We run an online marketplace where third-party sellers list products and buyers purchase them. The platform collects the full payment from the buyer, deducts a commission, and pays the seller. Refunds are common and complicate the accounting. Finance needs a model that reconciles every dollar from collection to payout. Design the data model.
How This Interview Works

- Ask clarifying questions to the AI interviewer
- Write your data modeling solution with real code execution
- Get instant feedback and a hire/no-hire decision
