It sounds like the problem is indeed the training environment as well as the on-line attitude and not the applicants background. I went from a turboprop straight into a hvy trijet, as did alot of my peers, and adjusted very well,we all did. The transition training was stringent, but we also had good, competent support from the line captains. If a line captain expects perfection from a newhire, then the disappointment of said captain is to be expected. Back in the days when we were pilots, we supported and mentored the new guys. I guess those days are becoming but a memory for some who forget they were also less experienced once.
