SLB interview questions

First, I had a telephone call inviting me to an interview session on a given date and a specific time. I turned up as instructed but had to go through a 10-minute seraching and registry procedure by the sentry at the door so it's advised to consider that 10 minute if you're gonna be exactly on time. The interview normally is conducted by the direct base manager and if you can pass it then another high ranking manager from the headquarters comes down to conduct a 2nd interview. If you also get through this stage successfully, you will probably be the main candidate. Then in 1 week time you will receive an offer letter stating your job title, grade and a break down of your salary and if you accept the offer then you are welcome to Schlumberger!
