Interview Prompt
We run a food-delivery marketplace, and product wants a live board of the dishes surging in each city right now, the kind of thing that reads 'pad thai is up 40 percent in Austin this week.' A single order usually bundles several different dishes, and the same dish shows up under many spellings across restaurant menus. The board refreshes every 15 minutes across hundreds of cities.
Summary
What's everyone eating? The answer changes hourly.
How This Interview Works
- Read the vague prompt (just like a real interview)
- 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
