Interview Prompt
A growth-stage company has 4 sources and 4 consumers; today every consumer team owns its own extract per source, producing 16 point-to-point ETLs. Three teams compute weekly active users with different numbers because the same source is cleaned three different ways. Apply the section's three-layer pattern: every source lands once into a shared raw layer, one canonical fact-per-entity sits in a shared curated layer, and all four consumers reroute to the curated layer.
