Interview Prompt

The data platform team wants each pipeline run enriched with a status-level benchmark. Keep every original column and add the total rows ingested across all pipelines sharing that run's status.

Summary

Every run carries the full measure of all who ended the same way.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
