It is unfortunately not the real cost of the course, you have to pay for everything, eg company ID, uniform, licence transfer, accommodation during and of course you won't get paid. So you have to count 50k instead.
The delay is up to 5 month now between sim and line training, no salary during that time, you're on your own.
Think twice before joining, it is P2F basically, I couldn't afford it, they kicked me out without further notice.
