Pros
The international mobile package is a good one if you are single and looking to travel. Base salary is not impressive, but once all of the benefits are added up it is very competitive. You get lots of good field exposure quickly and before you know it you are the go to guy on projects. Management of all levels seems approachable.
Cons
At least in smaller locations you can find yourself getting a baptism by fire so to say (put in a position of responsibility before you are properly trained or ready). This may be do to poor planning by management or project coordinators. Also, SLB can be slow to hire new people when needed. If everyone is working non stop and jobs are getting done then management will hold off on bringing new people which can really strain current employees.
