Fault Finding (Fault Diagnosis) Aptitude Test Preparation

Job Assessment Tests

If you’re going to be working with military vehicles or large machinery, you might be asked to take a fault diagnosis test. These pre-employment psychometric exams help companies screen graduates and job-seekers for the candidates who are most observant and discerning when it comes to finding and correcting errors.


What Is a Fault-Finding Exam?

A fault-finding test, such as the fault-finding Accenture exam or the SHL aptitude assessment, is an online test used to evaluate interested applicants. Whether they’re working on tanks in the armed forces or repairing a city bridge, technicians, civil engineers, and security personnel need to know how to spot and quickly fix equipment.

Though diagnostic aptitude tests won’t require you to have any technical knowledge, they will expect you to work quickly and accurately. The questions are all multiple choice. Each will present a system of arrows, switches, and knobs—a fictive machine—and you’ll need to identify which components are defective.


How to Prepare for a Fault-Finding Test?

To prepare for a fault diagnosis aptitude test, you’re going to need to practice. It’s essential that you familiarise yourself with the format of the questions on the exam. While you may have plenty of training and experience, your skills won’t come through in your results if the test finds you unprepared.
