> if you walk in the interview and make them feel stupid
... then you won't get hired, because nobody wants to hire an asshole with such poor social skills that they can't talk to someone without talking down to them.
how is showing your mental prowess talking down to "them"?, that is what interviews are for, you probably don't want to work for anyone who can't stand in a room with someone smarter then them, remember everyone is different, you will only feel stupid for a little while or in a state of lacking something, but in some cultures this behavior would be taken as a direct insult, i agree with you there, but hopefully you don't live in those countries, where everything is personal and macho...
