Schlumberger comes to Rice University every semester. Their appear on Career Expo, on info sessions and give on-campus interviews. Their appear an appealing exterior, so software students eagerly submitted their resumes and heavily prepared. However, unprofessionally, in their on-campus interview, both for full-time or intern, for software engineering, they never ask real technique questions, I mean, they ask basic concepts but not let you write codes. Seriously, from more than 10 computer science student I know who participated interviews, same scenario. It feels like they do not care about what you actually learnt what you can do, they care about how you bluff, just like how they bluff, that they beat Halliburton (vice versa, Halliburton said they beat Schlumberger). And finally, they strictly hire little, because they paid better than other oil-service software company in Houston. And you got no idea: why not me?
Last hint for Rice students: Choose more Steven's Wong's courses, and Schlumberger might give you an offer without onsite.
