Because so often we are faced with having to implement singularly linked-list reversal. I wouldn't even bother implementing this myself in the real world and I have a degree in computer science and 10 years experience doing dev work. I would type the problem into google, survey a couple of solutions and pick one I liked. Done. Next problem please. This is pedantic crap that is a waste of anyone's time. I can't believe people actually get asked shit like this at interviews? Well, at least none that I've ever been to. They look at my resume "Oh, CS degree at well respected University." and you can deduce that this person can probably work out trivial crap like this or look it up in a book or the internet. At most ask them for their academic records. What a complete waste of time in an interview..
