Yeh, while most of these seem to be obvious, unfortunately some of these do happen. I think that the best thing for any good geek to remember is that gret line from Star Wars: "Great, kid! Don't get cocky!" We may think that we know it all and are the greatest thing since 802.1x wireless, but we have to remember that we are only "that guy in the interview that needs to prove that he's an asset without proving that he's also an ASS."
