Interview Prompt

Our product analytics team wants a per-user funnel snapshot pulled from the raw event log. Produce one row per user, with separate columns counting their search, add_to_cart, and purchase events.

Summary

Every user leaves a trail of events. The report needs them lined up side by side.

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
