Interview Prompt
How would we carry sales from our point-of-sale and e-commerce event streams, peaking near 5,000 a second, into a data lake that keeps seven years of history, and on to merchandising, finance, data science and supply chain?
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
