I went to a career fair for my school where I talked to a recruiter. After talking to them for a bit, I didn't expect to hear from them but I ended up getting a call from them the next day about the interview 1. The first interview was questions about my background and questions like "Give me an example when you had to multitask" or "Tell me about a time where your priorities had to change in order to complete a goal." After this round of behavioral questions, it was my turn to tell them what I knew about SLB and ask questions about SLB. I would suggest that you do your homework about the company before you go so that you are prepared. And while doing your homework write down some softball questions that you might have about SLB that way you have some questions to ask. I was the last interview of the day so I went over in time and the recruiter didn't mind.

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
