The interview I under went involved a practical test, formal talk with personnel staff and a written exam.
The practical if you don’t have fingers like cows tits and can manage to tie your laces, won’t be a problem. The written test consisted of basic maths and engineering questions, nothing on rocket science. A Higher in physics will see you fly through this.
During the formal talk your attitude to others onboard a ship and engineering knowledge is accessed. Again not greatly in depth
If your thinking about joining then these are the questions I’d like you to ask yourself-
1. Can I drink everyday and still turn up in the morning?
2. Do I want to work in an environment very similar to and old boys club?
3. Can I make my own entertainment for weeks on end?
4. Can I take a much lower salary than others offshore?
I spent 5 happy years with global and wouldn’t change a thing (apart from I’d knock out a chief cable engineer). They didn’t have many good stations left as I headed out the door. I now do the oil and gas bit. I have to work for a living but am rewarded for it. The ROV training and experience you’ll gain will be in the noble art of trenching. Trudging around the seabed in a straight line for day after day. Oh what joy.
Give it a go, get a pilot tech 1 ticket, a few hours under your belt and see what happens. Just don’t get blinkered into not moving on as it’s very easy. Wish I’d only had 3 happy years.
