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
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
