A friend of mine was selected for the EVA ab initio program some years back. He was working for Evergreen Marine at the time. He didnt make it. Basically EVA would expect you to fly for them for a decade or two after the 18 month training , which takes you from zero time to the right seat of an airliner. I would say its a fantastic opportunity for a pilot wannabee.
The program is only open to ROC citizens though, far as I know. They are looking for young , healthy persons who want to fly as an airline pilot and who clearly show an aptitude for it. CAL had or still has such a program as well.
I am not sure if EVA currently is still seeking such candidates.
