All the training is in Hong Kong and lasts 4-5 months. It sounds like you are interiewing for a DEFO (Direct Entry First Officer) position. You will be locked on the freighter for 3 years but you can attempt an early command if you'd like. All DEFOs are based, so you will be rostered out of N.A. After 3 years, and based on seniority, you can exercise any number of options such as switch to the pax fleet (higher pay), move to HK, etc.

Good luck.
