I applied through college or university. The process took 3 months. I interviewed at SLB in Oct 2010
Interview
The whole process took over 6 months. They can move fast, but only if they want to.
Usually the will have one to one interviews with the recruiter first, then introduce you to technical people in the field you will be working. If they want you they can make things happen pretty quickly, though you will have to go trough all the required checks: technical, medical, background checks etc. They will make you feel that you want to work for them, and that they are the best company to work for.
