There was a career fair at my university, where the recruiter came and talked about the company and conducted the standard behavioral interview. Then, there is an on site interview where you are with a group of potential hires. You are put into groups before and have to present on one of the different segments of Schlumberger. Next, they talk about the segments, filling in any missing details and about the work life. We then did a group activity that was fairly stress free. The next morning, we went to an actual oil field to see what the work was like and talked to the people on site to answer any questions you might have. We had lunch and an exit interview talking about which segment we would rather work in.

1st round interview included short technical question, and telling about myself and the projects I worked on. Not difficult/or hard, but just need to explain well enough to tell the logic process
