I was contacted by a consulting agency that basically prescreens for Schlumberger. I had two phone interviews with them and then got an invitation to what Schlumberger calls "the 2nd Interview". Once you get an invitation they will give you all of the details like flight itinerary and information about the dress code and things of that nature. The first day is just a travel day but you will meet a lot of the other candidates this day. There was about 25 people interviewing when I went. Do not be alarmed by the amount of people going for the same job because there are a lot of job openings. I am not sure how accurate this is but it seemed to me like if you made it to this interview you have a really good chance of getting the job. The first day you fly in and the hotel shuttle will pick you up from the airport. You will quickly find out who is there for Schlumberger because they are standing around waiting as well. you will check in at the hotel and then have the rest of the night to eat dinner and prepare for the following day. The 2nd day is very long so get plenty of rest. You start the day by meeting in a conference room. Every person in the room will have to get up and give an introduction about themselves. Normal stuff like what are your hobbies, whats is your educational or military background, and the last but most important is what is your best Macgyver moment. They seem to be looking for creative answers. My advice is if you cant think of anything make something up. They want to hear that you are creative not prove you wrong. One guy at our interview didn't answer the question and it seemed to bother the recruiters and managers. After the introductions you will then sit through a lot of PowerPoint presentations about the company and learn about the different segments. Then you will take a break by getting fitted for coveralls and steel toes and you will be bused over to the Schlumberger training facility. I think the most important part about this is to take an active interest in it by asking questions and talking to the managers. The managers have been exactly where you are so its pretty much free game to ask what ever you want. The managers were pretty laid back and know what your going through so talking to them really is not difficult. After you tour the facility you will go back for more powerpoint presentations. Before dinner you will do a team building exercise. The most important part about the team exercise is to be engaged with your team. The managers are looking for team players and leaders. After that you will have dinner with the managers and recruiters and then get instructions about the next day. They will serve alcohol at dinner. My advice is that if you do drink dont get drunk. You want to be responsible. The next day you will meet up get your interview time and wait until your interview. I did not find the interview very difficult. Normal interview questions. I found that the intial phone interviews are a lot harder than the final interview. The final interview I felt was there to find out exactly what you want to do and where you want to work and whether you think you can handle the lifestyle. They are very honest about the different type of lifestyle it is. We had people drop out and not even do the final interview because they did not feel it was what they were looking for. The whole process I felt was there to make you feel more comfortable and relax about the interview. It was a good experience. After your final interview you will go back to the airport and back home. I think staying engaged and asking questions and talking with the managers will give you a good shot at getting the job. The company seems to want to put you where you want to go so dont put any locations down you dont want because there is a good chance you might get it. My last bit of advice is to be honest with yourself and be honest with them about what you want. The job is not easy but the company will work with you and thats a good feeling.
