SLB Field Engineer Intern interview questions

Applied online and got an interview offer. Went to a basic information session the day before the interview. Interview was completely behavioral based with a simple problem solving riddles where you explain your thought process. Interviewer didn't ask me if I had any questions and frankly seemed cold but I still got a second interview invitation in Bakersfield, CA. Before you go to the interview you are assigned a random team of other attendees where you will have to work together to put on a presentation about a branch of Schlumberger. You will spend the first evening doing these presentations from 8PM to 3AM at the latest. Stay focused and ask a few questions. The second day you are up and touring some of the surrounding fields and facilities. You are given a lot of chances to ask questions and get close up to the technology they use.
