The guy I interviewed with thinks he is a know it all because he was a lawyer for three years at some high firm before coming to LinkedIn. Then he goes on to saying how he was to good at what he did and wanted to be able to look at people in the eyes. He will brag about it during the interview so you don't have to worry. He'll come across rough but if you stay on top of your feet he'll like that. Also be aggressive and let him know you are a planner. Melinda the HR lady is great. She'll help you with anything you need.
