What Is the Marathon Job Skills Test (JST)?
Marathon's JST is an all-in-one assessment test that aims to evaluate your grasp of basic math, mechanics, and other essential skills through a barrage of multiple-choice questions. The test contains approximately 90 questions, depending on the position you're applying for, and takes a staggering 3.5 hours to complete. MPC clearly doesn't take this test lightly, and neither should you; proper preparation and a good night's sleep can go a long way in preventing test anxiety and test fatigue.
After filling out an online application form and passing the initial screening stage, Marathon will send you a link to the assessment. The exact contents of your test will differ based on your role and previous experience. A candidate for the job of junior refinery operator will take the Refinery Operator Trainee Basic Skills Test, for example.
MPC also offers positions in the fields of transport, engineering and construction, finance and accounting, IT, marine, health/environment/safety/security, marketing, and midstream operations. Each of these comes with a Job Skills Test tailor-made to evaluate the respective skills and competencies required.
A successful test result remains on file for a period of one year.
What Kind of Questions Are Featured on the Test?
Topics covered in the aptitude exam include basic math, reading comprehension, mechanical reasoning, gauge reading, an understanding of how tanks are filled, and a verbal memory exercise. The Marathon Refinery Operator Exam and several other specific job tests include questions on fluid mechanics/physics and a final section involving sets of lines. In this final section, the task is to identify the lines that overlap the other sets. Currently, we do not offer preparation for this specific task.
We've included a few sample questions on this page, for you to get a basic idea of what the test is like.
Sample Questions
Looking at gauges, thermometers, graphs, and other visual representations of data and quickly surmising the information you're looking for is an essential skill for many MPC employees. Read the following gauge and proceed to answer the question:
• What is the difference between the green lines on the psi scale (approximately)?
Having an understanding of math fundamentals is a prerequisite for many of the jobs offered at Marathon. Here's an example:
• Which of the following series lists the numbers in ascending order?
These questions are meant to allow you to demonstrate a basic and intuitive grasp of how things move. Answer the following wheels-and-pullies question, for example:
• In which direction should the leftmost wheel turn in order to continuously spin the rightmost wheel?
On this type of question, you'll need to read a set of facts, followed by a conclusion. Your task is to mark Definitely True if the conclusion can be drawn from the facts, Definitely False if it can be refuted by the facts, or Not Enough Information if it can't be proven or disproven by the facts. Here's an example:
At a certain company, the candidates for managerial roles must be assertive and/or experienced. There are 25 candidates for the role of department manager, of which 15 are experienced and assertive.
• Conclusion: All 25 candidates for the role of department manager may be experienced.
