Lots of good comments on this thread and none of the usual Flight Info BS.
Years ago when I started with Evergreen on the DC-8, they ran a strict military style program: You don't get 80% on the written exam, ya are out..No excuses, no re-testing. A bit nervewrecking and 2 guys in class were given a ticket home..One of them already had a type in the Diesel 8..Go figure.
At other non-scheds I have worked, including as a check airman, they (we) looked at attitudes as well as background/knowledge, etc.
Nobody got booted without being given a second chance.
As we hired more and more low-time guys the training issue was more high-lighted: High-time International guys with time in type did not need much training, just learn OUR procedures and call-outs, show up for training on time and you will get through...
When the low-time guys came onboard, we actually had to TRAIN folks, more or less from scratch.
Less of those guys washed out than the high time guys with an attitude.
It is really easy: If you try hard, the instructors and check airmen will bend over backwards to help you.
If you are lazy and think you know it all, you may be on the street real soon, wondering what happened.
