Interview Prompt

Put it all together: an intermediate freshness pipeline must merge CDC deltas without duplicates, version dimensions as SCD2, migrate schema online without breaking readers, and backfill corrected partitions idempotently under a quality gate.

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
