You need to fill in the form on their website. You then get an email when they arrange the skype call with you. One interview over the call and they basically tell you the answer the next day or even the same day.

Has been a unique interview in my case. Had a call from personnel department that I can meet an ops. manager in my city. Met this gentleman in a coffee shop and had a very informal interview with him. Halfway into it I was told it's not a question that I get the job,although in my case it was very positive that I had previous cruise ship work experience, even if not very long (only one contract). From there we were just talking about technical details (photography, software knowledge etc.), then we got to the point of starting date, when could I start the earliest. End of story: I was onboard a ship two weeks from the job interview, smooth and easy.
