Graduate job interview - but would rather have internship and complete masters

From what I've seen, 28-33K is an extremely common starting salary in the oil industry for a large services company, whereas for the operators it's typically between 35-40K, with the majors being at the higher end and the independents on the lower end. Not sure about salary progression since I'm not that far yet (although there are plenty of rumours floating about from my course mates but I'd be somewhat reluctant to believe them) but if you get to go offshore then you'll typically be paid between 100-200 pounds for every night you spend there. You obviously get much more opportunity to go offshore if you're a drilling engineer which is why drilling engineer salaries are typically quite high. You don't get so much by just staying in the office, but being offshore isn't for everyone and I'm quite reluctant to commit myself to a job that'll be almost exclusively offshore when I don't know much about it, nor whether I'd even be any use there due to my seasickness (can't get seasick on dry land).

Can I ask which company you applied to please?

Just a Norwegian drilling and well and reservoir management contractor.

I turned down the job in the end and they said that while they cannot guarantee that there'll be a position next year they'll welcome my application again.

Slightly regret it now given that my exams so far haven't went particularly well and the job only required a 2:2 whereas a I need at least a 2:1 to progress to masters.

Any particular reason why youre inclined towards doing a masters?
