JobTestPrep’s mock interviews can give you just the preparation you need, and our trained assessors are able to help you identify your strengths and weaknesses ahead of the real thing.

Schlumberger Assessment Centre

The second interview is held during an all day assessment centre which also includes aptitude tests, group exercises, a presentation, and a technical test. This all takes place at the Schlumberger offices. Remember that you are also being assessed on the day as a whole, so use the time outside of the various assessments to talk to others, get involved, ask questions and find out more. You will receive the schedule of day in advance, so read it carefully as you will be asked to prepare for the day.

Schlumberger Aptitude Tests

If you are applying to a technical role with Schlumberger, the type of aptitude tests you can expect are technically based. For those applying to a commercial and business position, you face a numerical and abstract reasoning test.

Numerical Reasoning Test

Considered by many to be a maths test, this test measures your ability to utilise numerical information in order to extract information and prove points. Information is presented in the format of tables, graphs or charts, and multiple choice questions are asked on the information provided. You have to be able to use the basic mathematical functions as well as percentages, ratios, fractions or currencies in order to answer these questions. Find out more about numerical reasoning tests and how to prepare for them with JobTestPrep.

Schlumberger Technical Test

Applicants for engineering positions are asked to put together a valve using a technical drawing and a bag of components. This task has a time limit of five minutes, and although it is not difficult, it is good to know about it in advance, as the time frame can create pressure on you.

Mechanical Reasoning

This test is most likely to be set for the technical positions available at Schlumberger. The Commercial and Business career path are unlikely to face this test as they will not need to know this information in their day to day jobs. In this test you are asked questions about mechanical and physics actions. Topics include forces and motions, energy, circuits, voltage, calculations of areas and more. Each question is multiple choice, and there is usually a tight time limit on the test. Find out more about mechanical reasoning tests on our website.

Abstract Reasoning

Abstract reasoning tests test you on your logical thinking without words. These tests are often called IQ tests, as they are considered to be the best way to measure a person’s IQ. In this test you are given a sequence or grid of shapes, and you are asked to identify the missing shape in the sequence from a set of options. Preparing in advance can teach you how to identify the patterns and answer the questions. Prepare for abstract reasoning tests with JobTestPrep.

Field Engineer Test

If you are applying for a job as a field engineer, you may take a slightly different type of test from those described above. This test is a combination of both numerical and mechanical reasoning, with questions on maths, physics, electrical circuits, mechanics and statistics. This is a 40 minute tests with 20 questions, meaning time is of the element. Practice for this challenging assessment with the help of our technical test battery.


The next activity at the assessment centre is a presentation. You are asked to prepare the presentation ahead of the assessment day.

Experienced hires may be asked to give a 30 minute technical presentation. You are notified whether this is the case in advance, and you are also told whether you have been given an assigned topic or allowed to choose your own. Once you have given over your presentation, you will then be asked questions on what you have said by your interviewer.

Applicants to graduate and intern positions are asked to give a 5 minute presentation. Topics will be sent to you in advance, but can include talking about yourself, your career aspirations, and your previous experience as well as a more technical topic. This presentation is given to the entire group present at the assessment day.

Giving a presentation can be a scary prospect, especially to your peers. Gain tips on how to give a presentation and sound confident on the day with our blog entry.

Group Exercise

The next task is a group activity. In smaller teams you are asked to work together to build a structure using paper and sellotape. This can be a shelter, a tower, or something capable of holding up a small item. The aim of this task is to assess how you work as part of a team in order to achieve a target. 

Schlumberger Interview

The interview is the final stage of the assessment day. It is a 30 minute competency based interview. The interviewer may ask you questions about yourself, the job description and your skills and experience matching the requirements of the job. They may also ask you about the divisions in the business area you have applied to, so do your research on the company ahead of your interview. Some questions will be technical based, and for these questions they are interested in your thought processes and how you work things through, not just your answers.

Ahead of the assessment day, don’t forget to review your resume, and to review your examples for use in answers. Look at the job description and prepare examples for the key job requirements. Brush up on your interview skills with a mock interview.
