That gives you a list of every job they have. If you click on Search Again and put the word "Trainee" in they keywords, you will get a list of 23 jobs including ROV Trainee positions for Canada, Singapore, India.
However, if you look at the job spec – such as the Far East one – they also say "ROV Tech/Pilot, Minimum 2 years experience working within an engineering environment"
So ex taxi drivers need not apply 😀
Oh, it also says "Ideally candidates should have no previous ROV training experience, due to the tailored in-house training programme"
so doing an ROV training school course is a waste of your money for this job :L
