I'd get ahold of their drill scheduled days and make sure to show up every day they have drill so they know who you are. Bring some booze for them and leave it on the bar with a note or a thank you and your name, go out of your way to introduce yourself to everyone. When the interview comes you dont want the conversation of "Anyone speak to this guy?" being talked about. Be yourself too as stated above, if you dont mesh with their culture no matter how much you want to fly their airframe you are going to not enjoy yourself. It's not 1 weekend a month, 2 weeks a year. You'll be spending a good deal of time with every person who is in that sq now for the next decade.
