Interview Prompt
We operate a fleet of food trucks. Each truck has a menu and moves between locations throughout the day. Customers order at a truck and pay. Operations wants to know: which items sell best at which locations? Which trucks are most profitable by day? Design the data model to answer these questions.
Summary
Mobile vendor, fixed menu, unpredictable locations.
How This Interview Works

- Ask clarifying questions to the AI interviewer
- Draw your data model on the schema canvas: tables, keys and relationships
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
