Interview Prompt
We run a two-sided marketplace where buyers and sellers transact. The analytics team needs a self-service warehouse to analyze GMV, conversion rates, and seller performance. There is no provided schema. You are expected to establish the entities, their relationships, and the dimensional model from scratch. Start by asking clarifying questions before designing anything.
