Interview Prompt

Put it all together: keep a warehouse customer dimension fresh from an operational DB. Move only changed rows via CDC, preserve attribute history (SCD2), let the schema evolve when a new column appears, and support backfilling a corrected partition without a full reload.

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
