ive been working offshore for 3 years now i work for halliburton and ive been with them since the start of the year doing completion & intervention tools ive never worked a 2n2 or any similair rotation i go away do the job come home i average about 3 weeks a month working away its good cash but you do miss home i done my rgit myself and found it VERY hard to get my foot in the door its near impossible unless you know somebody offshore allready.
sometimes you have to bullshit on your cv to get a start but most people with a hands on job like mechanic or engineer etc would have no problem its just getting the interview thats the hard bit but once your foot is in the door its easy street you can basically pick what job you fancy doing and apply for it ive worked for 3 service companys now but im sticking with this company they might not pay the best but they are the biggest service company in the world so at least i dont have to worry about work drying up lol and doing 3 weeks a month offshore it aint buttons you get in the bank either i average 4k to 5k a month before tax etc i couldnt earn that working onshore unless i started selling drugs.
good luck trying to get a job i wouldnt change it for anything
