Attended a full day interview with a group of other graduates who had applied for similar positions. Arrived at 8am and sat a pretty basic aptitude test which lasted 1 hour. We were then given a presentation on Schlumberger and the types of jobs which were available to graduates - this was all very vague After the presentation from the Schlumberger employee we then had to give personal presentations based on set criteria which had been sent the week prior to the interview. These were quite interesting, although, it did get a bit tedious after a while with them taking about 4 hours. We then did a group task which was to build a shelter out of a set amount of A4 sheets of paper and after this there were individual interviews. These seemed rushed and at 5 o'clock three of the panel left the interview room and only one interviewer was left. This seemed quite unprofessional. Finally got out at 6pm although there were still another four candidates to be interviewed after myself. A long day and received absolutely no feedback from Schlumberger.
