Applications to Allegiant have tripled, not just doubled. It would be my best guess that the preferred candidate is a 121 guy with PIC time and preferably instructor/check airman/chief pilot experience as well and a steady work history. That's what they liked in the past (when there were more pilots than there were jobs), no reason to assume it'd be different now. There are of course exceptions.
