1500 hour CFIs hired at Mesa within the past year are definitely in the miniority, or at least that was the case in my class and the others right around mine. Most have former 121, 135, or corporate experience.
It's not the end of the world, and when the upgrade at Compass drops below two years these same people criticizing 2nd year captains at Mesa will be applauding them at Compass. But that's quite alright, most of us sleep just fine at night knowing that people don't like us. BFD.
