Interview Prompt
A storage indexer hands you object keys as slash-separated `paths`, and you need them folded into a nested dict that mirrors the directory layout: every directory segment becomes an inner dict and every file sits at the leaf.
Summary
Flat strings carry a hierarchy. Recover it.
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
