Pros: large company
Cons: you have full benefits, but at at time it is cheaper not using the insurance.
Coming from the legacy Smith International into the Schlumberger family the train of thought of the employee is a 180 degree.
Smith International was family, you worked hard, you learn new thing and you advanced. You could come up the ranks of the company with a High school diploma and become a VP of a division.
Not the Schlumberger way.
