I applied through a recruiter. The process took 2 days. I interviewed at SLB in Sep 2011
Interview
They opened the hiring conference with an "ice breaker" set of questions. You told who you were, where you hoped to end up if hired, and what was you favorite color out the the four they offered. The color was associated with a task which you had to preform for the group (act out your favorite cartoon character, sing your favorite song, and stuff like that). Then you sit through a couple hours of of presentation about the company. After the presentation they break the group up into teams and have a Jeopardy style game to see how much you have picked up about the company and how you work together in a team. They then treat everyone to a buffet style dinner where they try to make things more personal with the interactions between the candidates and the recruiters/managers. After dinner they have more team building tasks where they want you to build something. Along the way they make additions or changes to what they want built. After the team building exercise they get you the coveralls for the trip to the training facility just south of Tulsa.
The recruiter that set up my trip to the conference highly encourage going to the bar before going to bed, so to prove I could be one of the guys with a drink or two.
The next morning everyone got on the bus and rode over to the training facility, spent 4 or 5 hours walking arould as a group. We got a chance to talk to techs who were recently hired.
After returning to the conference center they gave us a chance change for one on one interviews. The questions for the one on one where pretty general.
The whole ordeal is meant to be a way to root out people who do not want to or can not deal with high stress and high school like atitudes.
Interview questions [2]
Question 1
Given 8 blocks that look like they are the same size but one is heavier. Find the one that is heavier by using a balance scale no more than twice.
The process took 1 day. I interviewed at SLB (Stonehouse, England) in Jun 2011
Interview
Very friendly atmosphere, got to learn a lot about the oil & gas industry and Schlumberger's activities in the sector.
Did 2 basic electrical/electronics tests, calculating currents and voltage drops in resistor/capacitor circuits. There were also sections on high and low pass filters, op amps and general electrical/electronic knowledge. Pretty straight forward for an ONC/HNC graduate.
The interview process was quite laid back, but it is important to remain professional. I was asked about my salary expectations but I was not really prepared for this question; I informed them of my current salary and said I was sure we could come to an agreement.
The job itself appeared to be quite repetitive, but there is scope to progress in the company if ability is demonstrated.
