SLB Manufacturing Engineer interview questions

one round Hr type interview at my university which lasted for 30 mins. Four rounds of technical interviews at Sugar land, TX near Houston each lasted 40 to 45 min long and had to make a 7 min presentation any of my project. The interviews were one to one and were mostly on manufacturing processes

First I had an interview for a field engineer position on campus. Troubleshooting seemed to be a good talking point. I then proceeded to a group interview at their Sugar Land campus. At the time, I was again being interviewed for a field engineer position. We had to make a pipe cleaner bridge and perform other group tasks. I just tried to be myself, get along with the other candidates, ask a few questions about the company, be reasonably energetic, and show some genuine interest in the company and its work, casually assuring the interviewers that I could handle a job that wasn't 9-5, was outdoors, etc. It doesn't hurt to mention hobbies that require mechanical aptitude or hands on / outdoors experience. At the end of the interview, they asked me if I would be more interested in their tech and field program where you would work for 2 years in the field and then move to a technology center or a regular field engineer position. I said I'd be more interested in the tech and field program. Several months passed, with no communication and then a recruiter called with an offer to come work at their Sugar Land Technology center.
