The real problem: How you accurately evaluate a candidate without these questions? I dislike them as much as the next person, but I don't know a better way. Literally, all the best tech firms and ibanks do it. They pay the most and are most profitable. They must be doing something right. The real trick is finding a "fractically complex" question with many levels. The one in this blog is pretty good! No candidate can solve it perfectly in the allotted time, but you can have a good discussion about the "edges" of the problem -- where good candidates shine.
