They phone me 24 hours before the interview date as well as the send me a confirmation email to give me the schedule of this first step in the recruitment process. This schedule was rely simple: the next day at 9:00 1:1 interview, then at 10:00 written test. 1- Interview was really simple for the one who prepare himself basically: before to begin to ask you for questions about yourbackground, the Senior Associate Professional explain what the position will be involved to and it level in the company ladder (Trainee - Junior - Senior - Principal - Manager). It is recommanded to ask a maximum questions at this step to show your interest to the recruiters (and also to kill the time because if they are talking and answering your questions, you could be less expose to do errors). Then i will be also ask to explain your background (experiences, education) so you have to know your resume. After that you will be ask really simple questions as : "What do you know about HALLIBURTON? What have you manage a conflictual situation during your last job? What type of job do you like? What will you expect from your direct supervisor (in my case it was one the persons who are interviewing me)? Try to be clear in your answer and even if a question is unexpected : think first (and quickly) the way to give an answer and don't be scared to ask for clarification to the interviewers. 2- After that it was the written test. It was about basic engineering mathematics and physics. There were some global knowledge questions (focused this time on automobile - gears, gearbox, torque, stroke, engine). There were also scientific conersion to do (e.g: from ft/min to gal/min and so on).
