Interview Prompt

A third-party vendor drops a CSV file every morning containing 6 million rows of time series financial data. Our quant team needs this data queryable in the warehouse before the market opens. Design a full ETL architecture to ingest this file.

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
