Interview Prompt
A pricing analyst is auditing products that share a category but carry wildly different prices. Within each category, surface every pair of products whose prices are far enough apart to look like a shelving mistake, showing both product names, the category, and both prices.
Summary
Same shelf, wildly different stickers. Spot the pricing gaps.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
