As a petroleum engineer, Schlumberger was a very good company to work. This is why I was surprised when I offered an interview (not a brilliant student I am). They reimbursed the trip, hotel and meals for these two days, but it took 3 months to get the payment. Actually the first day begun with the signs of un-preparedness of the recruiter. The schedule we were told completely upside-downed, still was not a big problem indeed. There were 15 people which two guys applied just for internship. The atmosphere was relaxed, at least for me. Recruiter presented Schlumberger and underlined a lot the extreme conditions of the field engineer position. There were many unnecessary talk though, mostly the recruiter tried to answer all detailed questions of us. The IQ-like tests were incredibly simple. Still I believe, the main qualification were these tests for the recruiter. The secondary qualification I believe was the self-presentation part on the second day. Mostly our communication level is tested. Recruiter tried to put us under pressure by asking tricky questions, whereas the questions were far from being tricky for some of us. 1:1 interview I believe had no use in the recruiting process. Because I tried to ask questions and negotiate with him but he just give facts, no hard questions, no HR tricks, nothing. He was looking too tired at that time... I was offered and accepted their international mobile offer. I have not started my job since it has been postponed two times.
