Interview Prompt

One Airflow instance owns a 60-task mega-DAG spanning three teams: ingestion, analytics-engineering curation, and ML feature extraction. When the analytics dbt step fails, the unrelated ML feature extraction halts and pages cross team lines all night. Apply the section's split-DAG framing and split the orchestrator along ownership boundaries so a failure in one team's branch does not halt unrelated work in another.

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
