Interview Prompt
You're putting an HR export into a stable reporting order: a list of `records`, each a dict carrying the same fields, plus an ordered list of field names `keys`. Order the records by the first key, falling back to each next key in turn whenever the earlier ones tie.
Summary
When two things tie, something has to break the deadlock.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
