Interview Prompt
A service hands back deeply nested JSON config, and downstream code needs only a handful of values from it, each named by a dot-separated path like `user.name`. Given `data` (the nested dict) and `fields` (the list of paths), return a dict mapping each path to the value found by walking that sequence of dict keys.
Summary
Tell it what you want. It knows where to look.
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
