Straightforward and professional. Schlumberger sent my an email confirmation on what the interview process will be. 2 stages or parts form me. The first part or first interview is online from an HR representative. This will be about an hour to an hour and half of interview questions, basically what you know about the mission and vision of the company. The second process of the interview was with the manager of the location I was applying to. This will be the part where I showed my technical and product experiences and showcased how I have dealt with success and failures from my working experiences.
