Interview Prompt
A service loads its settings as a nested dict, where each level of nesting groups a section with its sub-settings and the leaves are the actual settings. Collapse `config` into a single-level dict keyed by each setting's full path from the top.
Summary
Every setting has a path. Trace it down to the value.
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
