As the course says, Induction.
You are not an ROV Pilot Technician of any grade after doing one course. There is no such qualification.
ROVs are technical bits of equipment, you need to have the appropriate technical bacground, qualifications and experience to get a start. You dont learn to be an ROV Pilot until you get a job as one.
Hence companies take trainees on for their technical background. You must start with that first.
There are also thousands of people out there chasing a handful of jobs. Please read through the other messages on here, especially in the Rookie section, as many of your questions have already been answered over and over again.
