I think this may have been a valid question a few years back when there were stacks of resumes of 500 hour pilots looking for work. There were regionals throwing the minimum required training at pilots, and if they couldn't hack it they were done. Almost like they were intentionally using the training process to weed people out at some places.

There isn't a regional around today that can afford that approach. Most will get you some extra one on one time to help you pass an oral, or 1 or 2 or 5 extra sim sessions if you need it. Nobody is trying to fail pilots in this current atmosphere. There are definitely cases people washing out of training. The airlines can only hold pilots hands so long. When I was at training someone had hit upwards of 25 Sim sessions before the company let them go, and someone else who failed the oral 3 times. At a point they have to cut these people loose. There are some people either not ready or not cut out for 121 flying. Those people are likely the pilots that wouldn't have made it through the interview process 3 or 4 years ago, but now that regionals are scraping the bottom of the barrel, they are giving those people a chance at training now.
