Interview Prompt

Our food delivery platform wants to show restaurant partners which dishes are trending in their city right now. A dish is trending when its order rate over the last 30 minutes is significantly higher than its baseline. We want this updated every few minutes. Design the data pipeline that powers this dashboard.

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 pipeline design solution with real code execution
4. Get instant feedback and a hire/no-hire decision
