Definitely appreciate your approach, I've asked similar questions when interviewing.

I also usually like to ask what a candidate likes and dislikes about Python, hoping for the GIL to creep up, along with an explanation as to what it is, implementations that don't have it along with methods of getting around the lock (although that would be a fairly advanced topic IMHO). If it doesn't come up, sometimes I'll pop it in depending on their level of experience.
