Where the Buck Stops

Interview Prompt
A directory export gives you reporting lines as (`manager`, `report`) pairs, and you need the org chart back. Return the reporting hierarchy as nested dictionaries, with the one person nobody reports to at the top.
Summary
A pile of reporting lines, no order to them. Somewhere in the bag sits the one with no boss.
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
