SLB Intern interview questions

Emailed mailed me about getting accepted for an interview. When I responded to set up an interview they never got back with me.

applied through college which required CV submission, after 3-4 weeks, schlumberger visited college and put a list of selected CVs, I was happy to see my name then we were divided into groups of 6 and each group was given a topic for GD for 5 mins. The topics given in the GD were abstract and not based on current affairs or anything. Some of the topics which I remember are Grey, Shades of White, Rain, Hash, lets do it, etc.
