I am not sure about this particular puzzle but I have noticed that I can learn a lot from observing how to approach such a problem. Even some senior people seem to have no ability to think about solutions. Other people seem to only be able to look up things on Google. I like people who at least try to attack the problem and think it through. I don't care so much if they succeed but I am happy if they are able and willing to think about something they haven't done before. From my experience this bodes well for working with them and them being able to adapt to new things.
