SLB REMS interview questions

Two days process. First day flew to Houston, visit rig in their campus, dinner together and team activities (just for fun, no observation from HR). Second day, gave a 7 min presentation. and then 4 1:1 interview. Looks like to me the interviewers are very random, they gave you the names of interviews first day but change them second day morning cause someone are not available and they temporarily ask stb to stand in
