tl;dr -- current programming interview format should be drastically changed. I have interviewed 100+ candidates so far. I'm doing interview less and less recently simply because I found those coding/design questions less meaningful to judge how good a candidate is. With websites like leetcode.com/lintcode.com that collect interview questions and provide online judge, all you need is to put enough time practicing. 10-years ago we use "reverse a linked-list" and nowadays we maybe use questions like "topo-sorting". The latter is significantly harder than the previous one -- but if candidate saw solution beforehand, it's actually easier to implement.
