Interview Prompt

We run a three-sided marketplace: consumers place orders from merchants, and couriers deliver them. Finance needs accurate revenue reporting. Operations needs delivery latency metrics. One order can be reassigned to a different courier if the first one cancels. Design the data model.

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write your data modeling solution with real code execution
4. Get instant feedback and a hire/no-hire decision
