Pros
It's a job. It gets you certifications and then you can move on to a better company, as Everyone here does. They have benefits, not as good as I've had with small companies, but good. Personal growth is something you'll need to find outside of your job, maybe taking classes online while working/ living on the rig. If you have no experience in the oil-field, this is an okay starter company if no one else will take you, grin and bare it for the first year or two then follow the trail of all you're work friends to other companies. My review is for field work (living on drilling rigs) I do know of some people that enjoy working in Schlumberger's office jobs.
Cons
Pay is better than McDonalds but low for oil-field work. The turnover is so high the people training you may be terrible at it and the Pathfinder/Schlumberger attitude it "oh well, deal with it". They are as an employer, the "Walmart" of the oil-field. They pay so little, and work their guys into the ground till they quit and then hire more new people. In the current market, they have an endless supply of people needing a job. They do not want experienced professionals, because they would have to pay them more, so they are a revolving door and buy out their competition. Once they absorb the old companies and then implement their nanny-state rules like no driving PERIOD after 11pm or before 5am because we're far too incompetent to accomplish this without wrecking and dying. They say they put their "People" first. That is a huge lie. They put Profits first, second, third, & fourth. They are getting more profitable while throwing their employees under their tires to gain more momentum.
