I happen to have a BSc in this field and of course we learned the linked list. Teachers love to teach it as much as US interviewers seems to love asking about it in interviews. (Around here they seem to be to dumb to know about it or to smart to ask for it, I suspect the latter.) That said I think gp's point is that if you ask for a doubly-linked list then you basically filter by having learned programming in school or not, or iow, if you told them how it was supposed to work instead of just saying the magic name then more of them would pass.
