Buddy of mine at AS went to the hiring dept a couple weeks ago, talked with one of the guys who's helping sort/score applications. Apparently, the 737 type is a "highly desired/strongly encouraged" item.
Didn't get a definitive answer about community service... I know a lot of us have been wondering about that because it was on the online application.
Of course they mentioned job fairs as a way to get a face-to-face connection, and apparently some applicants are going to the company HQ to meet the chief pilot and get their face time that way.
Just thought I'd pass along what I've heard. Doing what I can and hoping to get the call.
