Pre-Employment Assessment Tests: Types, Examples & How to Prepare

Pre-employment assessment tests are standardized exercises that employers use to evaluate candidates before making a job offer. They sit between your application and the interview in many hiring funnels, and for high-volume employers they are often the first real filter. Instead of relying only on a resume, the employer collects objective data on how you reason, how you tend to behave at work, what you know, and how you handle realistic job situations.

Employers use them for three reasons: to screen large applicant pools quickly, to compare candidates on the same measures, and to predict job performance more reliably than unstructured interviews alone. Decades of industrial and organizational psychology research show that cognitive ability tests, structured interviews and work samples are among the stronger predictors of performance, which is why they are so widely adopted.

In the United States, the use of tests is shaped by employment law. Under Title VII of the Civil Rights Act and the EEOC's Uniform Guidelines on Employee Selection Procedures, an assessment that disproportionately screens out a protected group must be shown to be job-related and consistent with business necessity. The Americans with Disabilities Act also requires employers to provide reasonable accommodations in testing. This is the legal backdrop for everything below.

Almost every assessment you meet falls into one of the following categories. Employers often combine two or three in a single process.

We have dedicated guides for the most common examples: the Wonderlic test, the Criteria CCAT, the Predictive Index, the Caliper Profile and the situational judgment test.

Cognitive ability tests measure general mental ability: how quickly you absorb new information, spot patterns and solve problems. They are usually short and severely time-limited, because speed is part of what is being measured. The Wonderlic and the Criteria CCAT are the best-known U.S. examples, with around 50 questions in 12 minutes and 50 questions in 15 minutes respectively.

Question types include verbal analogies and logic, number series and arithmetic word problems, and abstract pattern recognition. The same skills appear in enterprise tests from SHL and others; see our guides to numerical reasoning, verbal reasoning, inductive reasoning and logical reasoning.

Personality assessments describe how you typically behave, not how well you can reason. Most are based on models such as the Big Five (openness, conscientiousness, extraversion, agreeableness, emotional stability) or on proprietary frameworks. Your results are compared with the profile the employer believes fits the role, such as high conscientiousness for roles with exacting procedures or high extraversion for sales.

Formats include agree/disagree rating scales, "most like me / least like me" forced-choice blocks, and gamified tasks. Forced-choice formats make faking harder because every option is attractive. Because there are no right answers, the best strategy is consistent, honest responding that reflects you at your professional best. Read our personality test guide and DISC assessment guide for specific frameworks.

Situational judgment tests (SJTs) present short workplace dilemmas and ask what you would do, or rank responses from most to least effective. Employers use them for roles with a lot of customer or colleague contact. They test judgment, prioritization, and alignment with company values. Work samples and simulations go further, asking you to perform part of the job: prioritizing an inbox in an in-tray exercise, handling a scripted call, or analyzing data in a case.

Job knowledge and skills tests are the most straightforward: typing speed, Excel formulas, accounting basics, coding problems, or role-specific technical knowledge. See our Excel skills test guide and coding assessment guide. Newer platforms also use game-based assessments that measure attention, risk appetite and processing speed through short games; learn more in our game-based assessment guide.

Employers rarely build their own tests. They license platforms, and the platform often tells you what to expect.

Whatever the platform, the same preparation principles apply. Follow these steps in order.

• Identify the test type. Check your invitation email, the employer's careers page or recruiter. Knowing it is a cognitive test, a personality questionnaire or an SJT changes everything about how you prepare.
• Practice under timed conditions. Use realistic timed practice for cognitive tests until pacing is automatic. Our free practice tests are a good starting point.
• Prepare your environment. A quiet room, a stable internet connection, a charged laptop, a calculator and scrap paper where allowed. Close other tabs and apps.
• Read the employer's values. For SJTs and personality questionnaires, understand what the company prioritizes (customer focus, safety, teamwork) so that your honest answers reflect your relevant strengths.
• Request accommodations early. If you have a disability, dyslexia or another condition, ask for reasonable adjustments before the test. Our guide to reasonable adjustments explains how to request them.
• Never cheat. Many employers verify results with proctored or supervised retests, and cheating can cost you the offer. See SHL cheating consequences.
