The purpose of recruiting crew members by shipping agencies is to make money. If you want to be a sailor, you must have a crew certificate. Then the agency recruits crew members for the society. These people have no certificates and have to go to school for study, training and research, which involves the cost. The business scope of most intermediaries is not only crew recruitment, but also certification, makeup replacement and labor dispatch. In other words, after you pass the exam, they have a one-stop service until you get on the boat to work.
As for the authenticity of the information you mentioned, it can be said that 99% of the information contains false information, even liars. Say something big and you will understand that the crew has been saturated for a long time. Although it has picked up in recent years, the crew recruitment market is very chaotic, which is very profitable for shipping agents. Basically, the profit of seafarers recruited for the society is 1 10,000 or even more, and the profit of university-oriented training is 20,000. So why are so many agents recruiting crew members?
Why do you say that information must contain false information? Because it says that the profit is so big, you must spend more money. If I told you that being a sailor costs a lot of money, I believe few people would like to go. So I lured you with information such as the high salary of the crew. If the company is really short of crew, why should it recruit crew for the society? You have to train if you recruit. Can't use it right away. There are several major seafarer recruitment websites in China, all of which are certified seafarers and have not yet found employment. Wouldn't it be more efficient and reasonable to recruit seafarers if the information were sent to such websites?
In short, if you want to be a sailor, you have to go to school by yourself, not to those intermediary companies, to save money and prevent fraud.
