When I interview people, I ask them to describe a project they worked on. I ask them questions about the project and see if they're able to talk intelligently about the architecture. I talk to them about what I'm working on, so they'll know if it is something they want to do, and ask them questions about my project to see if they can talk about them intelligently. During this process, I get a feel for their technical abilities, how they like to work, and who they are as a person. I can tell if someone has skills without resorting to silly puzzles, obscure CS questions, or several hours of playing "Guess what I'm thinking." I also don't find any value in testing "How someone solves a problem," since people solve things differently. I have no guarantee that my way is the best, so why would I reject someone else just because their brain works differently than mine does?
