I struggle to find the point of this article. OK, I'm somewhat being coy and perhaps somewhat dismissing it with a middlebrow but in a real sense I'm not quite sure what is being argued. Is this the developer of "Find the Mafia!"? It's not as if the "Top Tech Companies" are actually measuring IQ, so that seems to belie the point. Sure, you could say they are asking questions that you believe correlate with raw IQ if you want, I might say "citation needed" but the fact is it is not exactly what they are doing. Now, I'm not sure this particular type of puzzle is the perfect solution, or even a candidate solution. Yeah, I'm a little flummoxed. By the way, the simpler explanation for asking question about CS theory and algorithms is that they want people that have really studied them thoroughly. I know, it's a crazy idea, ... but it just might be the answer. :)
