Interview Prompt

We're building the data warehouse for a trading platform. We handle stocks, ETFs, and crypto with fractional share support. Trades settle in multiple currencies, and the SEC requires point-in-time snapshots for audits. Design the dimensional model.

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 data modeling solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
