Simply put from a Capt (foreign flag) perspective:
I have had more success hiring crew from resumes when I ask for Ozzies and Kiwis. They cost the owner less, they work longer hours, they have a better attitude to me and the guests; also as the majority of the crew on my commands will be from overseas they will "get" the other crew members; and their enthusiasm and moral feeds off each other's hard working, co-operative atmosphere. Not very PC, but that is my limited experience.
Now before all you American & other guys jump down my throat, I know that the above is a gross generalization, but I have to play the averages when hiring to give myself the best chance of having a great crew. It has worked this way so far anyway.....
