Interview Prompt

Demand planners on the commercial team can't separate promoted units from baseline, or tell how stale each row's source is. Sell-through arrives as daily distributor EDI files, weekly retailer portal exports from 50,000 partners, and streaming direct-to-consumer orders: design one pipeline that fixes both.

Summary

Retail data at CPG scale. Every SKU, every store.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Draw your pipeline on the design canvas: sources, transforms, storage and checks
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
