If you've got that much experience and someone asks you how to impliment a linked list, I'd say you should politely leave the interview. Graduate questions like that are insulting once you've got past the junior levels, as companies asking them are either too lazy to put a proper interview together for more senior levels, or not senior enough to know the difference. That's not to say they can't ask you about data structures, but they shouldn't be asking you to code them up from first principles if it's something the language can do for you. I find it much more fruitful to have a technical chat with candidates instead of being dogmatic about asking toy questions. It's pretty obvious when someone doesn't know what a linked list is with a 30 second chat. Heck, even drawing a few boxes and arrows on a napkin will suffice.
