Interview Prompt

A data normalization service receives arbitrarily nested list payloads from a legacy API. Given a deeply nested list of integers and lists, return a single flat list containing all integer values in order. You must handle any depth of nesting.

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
