Pros
-Schlumberger's new hire advancement program guarantees salary increases/promotions over the first three years. -Hours can be very flexible, but that depends which center you're working at and your manager. -Schlumberger is filled with young professionals (Partly because they hire people straight out of college almost exclusively and partly because they laid off all the more senior people) anyway... if you are a young professional, it's easy to make friends.
Cons
-Don't count on Schlumberger for a long term career. If oil goes south, they will not hesitate to lay off large swaths of people, starting with people who cost the most. I have been working at Schlumberger for a couple years now and have been through so many layoffs, I've lost count. (but if I had to guess, probably at least 8-9 rounds of them) -Senior management tries to push initiatives that ultimately make yours or someone else's job harder, often with very little benefit ever seen. -The company is huge and there's a lot of bureaucracy. -Schlumberger's initiative to hire women and promote them to higher roles within the company is sometimes sexist towards men. You know there is a problem when women you are friends with within the company feel guilty of promotions they have received over other coworkers.
