As I know,Before they were just collecting CVs and then they consider if you are succesfull and suitable for them.They were doing telephone interviews or it depends where you apply them from.If you live in somewhere where they fly they send you invitation and tickets to go there and have tests..
I am not sure I heard these from a friend who applied them before..
But the application is still open it means they are still collecting..if you dont hear in 4 weeks from them this means you were eliminated..
