I'm not sure about the specifics of what it takes to get the call for an interview, but I am guessing you need someone to physically walk your resume into a chief pilot and make contact with them to say 'hire this guy because I say so.' I have had my online app completed for about 6 months and was a past intern there with a letter of rec from my old boss, since he is in the downtown HQ maybe he doesnt make many trips the the airport to see the chief? If anyone figures it out let me know too!
