Interview Prompt

A two-person team has Stripe, a Python ETL, and a Looker dashboard wired straight to the ETL. Stripe rate-limits at 100 req/min while the dashboard refreshes 200 times a day, so every refresh re-pulls Stripe and trips the limit; when the ETL crashes mid-run the chart goes blank. Apply the section's four-roles framing and add the role the canvas is missing so the dashboard can refresh without retouching Stripe and keep serving when the ETL is down.

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
