I see and acknowledge where you come from. That being said, maybe your perception of the process is a bit flawed.It is most likely true that for the most people who "quants" or aspire to become one, intelligence, or the perception of, is a pretty dominant part of their life. They went through school being the kid that is good at math, studied physics or mathematics or a similar "nerd" topic at a top institution and kept being one of the best. They enjoy what they do. And they develop some kind of arrogance, or confidence, or whatever you want to call it, about the fact that they are probably a bit more "intelligent" than other people. It is not unlikely that at more than one point in their life, they were "better" at what they did than some kind of teacher.This is a problem, because if you are that picky about your interview questions, how long into the job til you decide that this one stupid task doesnt live up to your aspirations of only doing the most cutting edge challenging work? A hiring manager cant hire something that might walk for such stupid reasons, and for that reason, youre out. This doesnt need to have anything to do with hurt feelings or some kind of inferiority complex. Managers are evaluated mostly by the bad hiring decisions they make. By making the hiring process deliberately boring for the "more intelligent" candidates, they can weed the ones with ego problems out.On the other hand side, if theres some guy who knows he cant beat the more difficult brainteasers and decides to overcome that hurdle by just memorizing all the brainteasers he can find, thats a person id want to have on my team, even if he lacks specific skills to do that one task he should have to be able to perform. Give him a book and 2 weeks later hell be able to perform that one.
