Interview Prompt

A config tree is stored as a nested dict and we need all the leaf values for validation. Traverse the dict to any depth and return all non-dict values as a flat list in traversal order.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
