Sorry to hear that, you just got to keep applying and don't take it personally. They received over a hundred apps, so it's just competitive. When I was visiting a squadron, I asked what were things they looked for and one guy said most of the time it's razor thin, everybody has good scores, experience...etc they could pick a different group apps to interview depending on the day or mood. It's tough with the internet becaue they're casting a wide net, back in the day you'll just grab a drink and hang out with them and they'll think "MeekTiger is a cool cat, let's make him a pilot...etc"
Also, update for the 327th, I received a phone screening, they're calling whoever made their score cutoffs, but they received well over 100 apps and only plan to invite a few for interviews since the board date is close and they don't want to waste people's time and money bringing in a bunch of people to interview. They expect to send interview invites this week.
