I don't know why technical interviews/recruiting are such a fascinating subject. I think it is related to the fact that they are such an imperfect mechanism for finding employees/partners.

Well known cliches like the 10x more effective programmer and the Microsoft/Google methods of recruiting add to the mysticism.

This particular article has some good tips though I'm not sure how practical it is. Modern recruiting uses extensive keyword searching. Unless your goal is to weed out some of that, this kind of job posting may not get too many hits.
