Interview Prompt

A paged API returns `pages`, a list of pages where each page is a list of items. Inside `paginate(pages)`, build a class that implements `__iter__` and `__next__` and hands out the items one at a time, keeping its place between calls, then return everything it yields as a list.

Summary

Nobody loads everything at once.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
