Add to the above the fact that many courses are done via zoom etc which degrades a lot the quality of the training. At least that's how I felt as a new fo in a small company which grabbed the opportunity post-covid and did most of the courses like this in order to cut expenses among other things of course.
I also still remember the first days in a RYR TR a long-long talk about how magnificent the company was and how fantastic was the fact that we would be able to fly the MAX after just a couple of CBTs. Yeah sure...
