Interview Prompt
Orders and menu updates live in separate operational systems that are never joined, yet the recommendations team needs a feature store it can query in real time. At our meal kit service, those systems hold customer order history and the full menu catalog with nutritional and ingredient data. Design the ingestion and feature pipeline.
Summary
They ordered pad thai twice. That means something.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
