Before advanced to interview, there are various difficult test. The tests are theory and practical. In theory we have to answer difficult questions. In practical we have work as a team to get desired goal

Mix of behavioral and technical questions. Got back to me in a timely manner about their decision. Very good feedback on my responses and how they matched with the values of Schlumberger. Overall enjoyable process.

The first round is just the behavioral question given by HR only. Basically most of the questions come from my resume. Therefore, be prepared for every point in the resume, especially those experience which can show your teamwork ability, leadership skills, ability to adjust new environment, engineering project/work experience etc. The questions are not difficult generally, so try to keep the whole conversation in a relaxing atmosphere!
