Thanks guys!!
According to Central Scrutinizer advice, I will seek and contact pilot and ask them.
Actually I want to join Hongkong airlines.
They have their cadet program for HK residents on CTC/L3.
I can only attempt to CTC take off course, but it's bit expensive.
And of course, no guarantee and I have to get another job to build flight time.
So I consider another cadet course what foreigners can apply or linetraining.
