These tests help narrow the field of applicants to those with the best combination of aptitude and personality traits. The tests will vary by position, but these are a few of the most commonly given assessments.

• Mechanical Reasoning Assessment Test – This test is designed to evaluate your knowledge of moving systems like pulleys, gears, and levers, basic physical concepts like gravity and velocity, and depending on the test a knowledge of electrical systems. This test is multiple choice, and there will be a time limit.
• Numerical Reasoning Exam – The difficulty of this test will vary based on the level of skill needed for each job. The focus is on mathematical aptitude and your ability to work with numbers. This can range from word problems and graphs, working with fractions and decimals, simple problem solving like addition and subtraction, and more difficult concepts like multiplication and division. You will be working with a time limit, but this test is multiple-choice.
• Personality Survey – Personality questionnaires are used to help make sure prospective employees will work well with established employees, and thrive in the company culture. The survey will ask you to rank statements as least or most like you.

How to Prepare for Steel Dynamics’ Assessments?

It is always a good idea to practice for the assessments prior to taking them. This will give you a leg up on other candidates in a competitive field. Start by getting familiar with the job description, this gives you some idea of the areas you may be tested on.

Most jobs require some level of mathematical aptitude. You can practice using flash cards, by doing word problems, and by working on skills like estimation. Being able to estimate to quickly determine the answer is helpful on a timed test.

Skilled trades, plant workers, and engineers will most likely be given a mechanical reasoning test. For this you can use your old study materials from your licensing course or any classes you have taken,  or find tools online to refresh your memory on basic physics concepts and simple machinery.

Personality and situational judgment tests may seem like things you cannot study for. You definitely should not take the tests only selecting the responses that seem the most positive. Instead, learn about the company and their expectations. Then when taking the assessments respond honestly, but as if you already have the job. This will give them a real look at your work style and personality.
