Interview Prompt

Our year-over-year output figures for the video side are inflated by articles and podcasts. Rebuild them from `content_items` counting only video, short and livestream items, giving each creator their 2026 count minus their 2025 count.

Launch velocity, year over year.

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
