I am no expert but there is a multiple silo theory of how they pull apps. They have a short stack pile of apps, an intern pile, a well qualified pile, and a good but less qualified pile. I think they go through waves of who they call and they pull from all piles at once. Some people are interviewing with all regional first officers and some are interviewing with a complete mix of people from all over the spectrum. There isn't a rhyme or reason to some of the calls but they are all good candidates for one reason or another. Just keep the app up to date and try to check as many boxes as you can. Weird things happen!
