SLB Trainee Field Engineer interview questions

Was interviewing by Schlumberger HR by phone. Nothing special, questions like "Why you want to work in Slb?", "What is the most hard decision you ever have to make?". Interview was on both Russian and English.

They show up at my university. I took a test, a 1:1 interview and then went to their location for a 2 days interview. It was a group interview where they test our math, english, ability to sleep depravation, physical capacity, etc. Very intresting and hard. About 30% got offer to start the job. Some are going to be relocated
