Do you mean the seaman's certificate by sea training? The training of seafarers' four certificates takes about one month. If you have training before the interview, these are all organized by the intermediary company itself. As far as I know, the longest training is one year. Ha ha. But the cost is also high. If you are talking about this training, the training content of each cruise company is different and uneven. This is hard to say. You won't know whether their training is useful to you until you learn it.

The training of the cruise company is the pre-job training organized by the cruise company after the interview and before you board the ship. These trainings mainly give you a brief explanation of your work and life on the cruise ship, as well as some training plans and contents of the cruise company. These are all formulated by cruise companies, and they are all free.

I hope I can help you. You can keep asking me questions about cruise ships. Now Costa Cruises in Italy and Caribbean Cruises in the United States are hiring.
