I met for a 1:1 interview in early September at my university. More of a conversation for my interview, but I heard others had a case study or more technical questions. Most common question is why Schlumberger? I got an email the next day to schedule my second round interview at a site in mid-October. When the second interview rolled around it was a 3 day process. Day 1: flew in LA in the afternoon and had a few hours in the hotel. They assigned me a roommate because the group was about 30 or so people. That night (6 pm - midnight) the recruiters had us do an icebreaker, give segment presentations (they don’t care the content, just your teamwork and presentation skills), and then the recruiters gave accurate segment presentations. Day 2: we loaded the bus at 8 am for breakfast and site visit. Be engaged and ask a lot of questions. Then we did lunch and went back to the hotel. You fill out a preference sheet of what segment you would want to be in and why. Then you meet with a recruiter for an exit interview (15 min) to talk about your preferences. After the interview everyone is invited to a nice dinner with drinks. The recruiters have more fun at this point, but they’re still watching so be responsible and engaged. Finally, some recruiters and interviewees go out to a bar and some go back to the hotel. I went back to the hotel because my flight was early the next day and I still got an offer so don’t think you have to go out after dinner. Day 3: Fly out I heard back 3 weeks later from leaving the second round that I received an offer. They said they would have them sooner, but just count on 3 weeks so you don’t stress out.
