(I wrote the top comment) I agree that's not a great question. I usually have few simple questions that can tell you if your candidate really understands the platform they say they understand -- it doesn't take much. I usually have one or two projects set aside specifically for new hires; the type of project that is maybe a month-long or longer but that doesn't really require any domain knowledge or big integrations. It allows them to have something to do when they're learning everything else. In the interview, I can ask them how they'd proceed with it and I always offer that I'm here to help them and will answer any questions they have. This is literally no different than what I would ask them on day one of the job if they got hired. Is that more informative than whether or not they can reverse a linked list? I think so.
