I applied through a recruiter. The process took 2 weeks. I interviewed at SLB (Aberdeen, Escocia) in Nov 2014
Interview
Process was very straight forward. Applied online and submitted a CV. No cover letter required. Talked to one of the engineering recruiters at my university's careers fair. She passed on her contact card and took my CV. I later received an email for an invite to an assessment centre in Aberdeen.
The assessment centre consisted of an introduction to Schlumberger and how their business operates. Be prepared to ask questions and answer queries regarding the companies history. There were timed IQ style tests that lasted approximately 1 hr. It is key to be prepared at this stage and make sure to practice as much as possible. There were no numerical style questions. One of the tests consisted of 3x3 matrices where you have to discover a pattern in a small amount of time.
Later we carried out our self-presentations that were prepared in advance and assembled a valve with an interview to follow.
Interview questions [1]
Question 1
each candidate had to assemble a diaphragm valve (for gas) within 5 minutes with parts missing. Its important to remain calm at this stage and not to be thrown off. If you do not assemble it within the allocated time, talk about what you would have done to complete the valve. You are provided a cross sectional drawing and not an exploded diagram. They later asked the usual HR questions and what product line interests you the most.
I applied online. The process took 2 weeks. I interviewed at SLB (Gatwick, England) in Nov 2014
Interview
Application involved submitting a CV.

Question 1
Why are you deferring away from your original sector of engineering?
Resume shortlisting for campus placements. Followed by group discussion on an abstract topic. Further involves a group activity(discussion based on a hypothetical situation ). group activity is one of the toughest rounds. The interview is purely HR, no technical. Mostly discussing what you did and how you did it. being a part of a sports team helps.
