My friends' son flies with EVA and he is quite happy there. Started in 2017 after they recruited the first B777 NTR FO's (was not type rated at the time).
He went via an agency (as in most Asian countries due to regulations) and was well prepared by them for screenings, SIM, medical etc.
The transition for FAA pilots is easier as Taiwan follows FAA regulations more than other Asian countries.
Then again, you must be open to experience another culture, which at least for myself, enriched my life. Nowadays it seems that not as many pilots are open to this.
I started in Europe and was based in Japan and Australia before moving to another airline in HKG (now retired)
