FWIW, I heard Rocky tell attendees at a previous job fair that this is what they're looking for when they screen applicants:
1. Flight experience - quality, not necessarily quantity.
2. Education - yes, a bachelors is not a listed hard requirement, but he all but said you will not get called without one. Are there exceptions? Probably, but they would be few and far, far between.
3. Leadership experience - this is where military has the leg up, but there are certainly opportunities for civilians.
We could probably only guess at the qualitative/quantitative value of each factor, but I got the distinct impression that they were looking at the whole person, and not just hiring guys who had passed a certain TT or PIC milestone. I'm a mil guy who has pretty good representation in each category and I got the job fair invite with under 2500TT.
