Interview Prompt
An analyst keeps getting a differently ordered outreach roster from `customers` on every run, because plenty of customers share the same first and last name. Produce each customer's full name with their ID and country, alphabetical by full name.
Summary
First name, last name. Combine them.
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
