Interview Prompt

A SaaS company has Salesforce CRM and Stripe payments feeding two parallel paths: a Finance ETL that joins them one way and a Marketing ETL that joins them differently, each writing its own fact table. Every Monday the CFO and the head of marketing report different totals. Apply the section's fan-in framing so the two sources join exactly once into one canonical fact table that both dashboards read from.

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
