Large companies suffer from having too many people in an office with nothing better to do. They can quantify and file paper qualifications. They have no clue how to translate real experience into something they can file away.
Seen it happen multiple times where I work. We lost out on a few very good temp workers simply because they did not posses a college diploma that was listed on the job requirements. To big business, paper trumps ability every time. Right now one of our guys who has been the working grunt and goto guy for repairs to a certain system, and currently filling in for somebody who has left the company, is going to be denied the job that he is filling in for simply because he does not posses a college diploma that is based on a course one year longer. "hey, you know how to do this, and you do it well, we need you to fill in for mr.x, starting tomorrow." (literally) "Oh sorry, we can't hire you for this because the job requirements state a 4 year diploma, you only have a 3year, oh, we need you to keep doing the job (you are not paper qualified for) until the end of the month". And like in our shop, they will probably end up hiring somebody with the personality and ability of a post that doesn't know their ass from a hole in the ground...
