i had an interview at schlumberger in 2013 as a trainee,it was a basic screening interview,the interviewer asked me to introduce my self, there was no technical questions.it was an easy as a first interview.

The process began with applying through their official website. We received an email containing the date and location of the Aptitude test. Passing the test qualifies us for an interview with the Human Resources department. Note: The test date and time were specified in the email for the day after we received it. To be honest, you could have postponed it if needed, and this doesn't necessarily happen to everyone, but it did, which is why I mentioned this so anyone can keep this in mind when applying. The Aptitude test consisted of 50 questions, with a 50-minute time limit, distributed as follows: 20 questions in English 20 questions in mathematics 10 questions in intelligence. The questions ranged from easy to medium to difficult, and overall, the test was not challenging. After completing the test, we waited for the grading process. Those who didn't pass were thanked and encouraged to reapply before leaving. Those who passed went directly to the Human Resources interview.
