Schlumberger flew me out to Tulsa, OK from Houston, TX for multiple interviews. Meet and greet dinner and team building exercises over two days culminated with two separate formal interviews. Each had 2 to 3 interviewers asking me questions about my electronic background and knowledge. Drug testing: Before flying out to Tulsa I had to get drug tested with a hair sample and breathalyzer. I also had to pass a fitness test which consisted of hanging from a rope using only my bare hands for 30 seconds. They also made me climb several flights of stairs while carrying a 30 lb. weight. Before the interview the drug tested me on the first day. They also drug/alcohol tested me on the last day using urine samples and a breathalyzer.
