Interview Prompt

The merchandising team wants to know which products carry each category by sales, where a product's revenue is its quantity times unit price summed across every order line. For each category return its three strongest products, showing the category, the product name, that revenue, and the product's standing within the category.

Summary

Every aisle has its champions. Surface the three that carry each one.

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
