SLB Mechanical Engineer interview questions

Applied at the career fair, and got the 1st round interview days later. The first round was mostly about resume and behavior questions. Half a month later I got the chance of an on-site. Flew to Houston. People were nice. The on-site lasted 2 days, the second day was about the interview. 7 min presentation followed by 4 round back-on-back interview. Each interview lasted about 45 min.
