Why would they? It might be happening but, just to remind everyone here, it's the exception, not the rule. So, unless your application is really awesome, most unit's probably aren't going to pursue one.
Scores really aren't enough on their own, either. When we get 100 applications, I would say at least half of them have really good scores. So now I need to find another way to pick 12 or so people to invite to an interview. So I read through maybe the top 20 or so based on scores, GPA, maybe some other factors, and really try to figure out what kind of person you are by reading your cover letter, your letters of recommendation, and seeing what you have accomplished over the years. Then, we'll narrow it down to a dozen people or so and send out invites.
My best advice is to try and find a way to make your application stand out and grab my attention. I honestly dont care how it's prepared but it should be neat and orderly, but no need to spend much money on it. It sucks when reading through the top 20 applications and they all read the same. Good scores, good GPA, and guess what? All letters of recommendation sound the same.
When reading your cover letter, I honestly don't care what you type about why you want to fly with us. It could all just be bullshit that you just researched online the night before. I think it'd be awesome to see a cover letter, in bullet format, telling me about all the cool things you have done, the stuff the doesn't have a place on a resume. The stories you would tell your bros over a beer. And don't be a douche.
These are all random thoughts after having a few beers. I encourage everyone to keep applying, no matter the odds. Age waivers are not common and I wouldn't expect a Squadron to be willing to work one, but you never know. You're application is really going to have to stand out and even then it's still a long shot. Use this information to make the best decision you can if you want to get in this business. Maybe the UPT ship has sailed, but there are other options out there that can still be pretty cool.
