I agree that people are not "left in the lurch" after the TR anymore, but this is due to the procedures being improved.
FR always need fresh pilots due to the continued expansion and people leaving. Nothing has changed except for the manner in which people are now processed. Allot of people fail the interview/Sim, a few fail the TR and a couple fail the base check... and of course, there are some who fail the line training.
Much as people love to assume, FR will not give you a job just because you have a little blue book, however, most with the aforementioned book can and generally do get an interview.. Many never get any further..
