From the article: "I'm going to ask you to solve one of my problems for every problem you ask me. Remember, an interview is a two-way process, I'm trying to determine if I want to work with you too." This is the best part really.. Instead of "just say no" remember it's a dialog. If the brainteaser is interesting or you can quickly respond to how you would approach solving it then don't be an jerk about it. And feel free to have a dialog ask something back and see how they approach problem solving etc. Make it fun and interesting for all involved. If you're going to work with these people you might as well start right now in the interview! I never take an interview with a potential client or employer without having a very clear set of my own questions for them and getting those answered. I often ask off the wall questions or talk about a deep problem we solved recently and ask for the candidate for ideas on how they would approach the problem. I always share the answer we came up with. The reason for the question is not a perfect answer but to see how a candidate approaches potentially solving the question.
