Interview Prompt
The finance team's line-item report only shows product IDs. Enrich each transaction with its product name from the catalog so stakeholders can see what was actually purchased.
Summary
Transaction IDs are useless without context. Bring in the product names.
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
