I am sorry that I am not familiar with the hiring procedures for RCI or for your position.
My experience is that if you are getting communication from the cruise line ten they are still serious about hiring you.
But, I do not know who your recruiter is. My question would be whether the actual cruise line is still saying they are interetsted in you. I have never worked through recruiters before.
I am the editor, but I also speculate, ask questions and play devil's advocate. I reserve the right to change my mind.
