Interview Prompt

Build a class that takes a list of pages, where each page is itself a list of items, and lazily produces one item at a time across all pages in sequence. The class must implement the standard Python iterator protocol so it works in any for loop or next() call.

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
