As I’m a recruiter for an international ROV company, I would offer the following advice:
1. Turn up on time
2. Dress smart but casual – smart jeans/shirt is good (a suit is for an office job!)
3. Do your homework on the company (I will ask you which ROV’s we operate and where etc)
4. Be prepared for some basic tech questions on ROV’s (very general)
5. Be prepared to answer an example tech query – "what would you do if" etc (very generic)
6. Have answers to HR type questions – e.g. "why should I hire you", "what are your thoughts on HSE" etc
7. Don’t tell me how fanatastic you are or put your feet on my desk.
8. Just be yourself and don’t bullshit about anything (you will get found out very quickly once offshore)
9. Keep good eye contact – but don’t stare at me too much (I’m easily scared!)
10. If you can do the above, you will probably get a start with a bit of luck š
Anyway, this is obviously just my thoughts and not necessarily the way other players operate, but I hope some of this helps.
