Japandwell,
The ones with me had experience on Dash8, Cheiftan and a few more. Some had done part 135 ops and some not. Two had been instructors and all were over 25 years old bar one. Yes we were all AE as none of us had an ATP licence yet.
I don't really think they care what you flew before, just if you will fit in and be able to cope with the training.
Is that what you mean?
