Interview Prompt

We group users by account status, and every segment leans toward one product category more than the rest. For each status, surface the category with the most purchases, where a purchase is a single transaction regardless of how many units it moved.

Summary

Each segment has a favorite category.

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 sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
