Interview Prompt
Given a positive integer n, build the sequence 1^2, 2^2, ..., n^2 in order. Internally generate the squares lazily with a generator (one square at a time), but return them collected into a list. For example, squares_up_to(5) returns [1, 4, 9, 16, 25].
Summary
A sequence that never fully reveals itself.

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