What Is a Psychometric Test? What Employers Measure and How to Prepare

They fall into two main categories. Ability tests measure cognitive skills: numerical reasoning, verbal reasoning, logical reasoning, spatial reasoning, and abstract pattern recognition. These have objectively correct answers and are typically timed.

Personality assessments measure behavioral tendencies, preferences, and working styles: how you prefer to collaborate, how you handle stress, how you communicate, and how you approach risk. These have no objectively correct answers, though most have response patterns that employers consider more aligned with specific roles or team cultures.

Both types are common in graduate scheme hiring, management consulting, financial services, and large-enterprise recruitment. They typically appear after an initial application is accepted and before any live interview, functioning as an early filter alongside aptitude tests. See the aptitude test page for guidance on ability-based tests specifically.

How interviewers usually evaluate this

Interviewers rarely grade the term itself. They grade how well you apply it under pressure. That means understanding the concept is only the starting point. The stronger signal is whether you can use it clearly, consistently, and in the right part of the interview.

The points below give you the most practical starting place for applying this concept well in a real interview. Use them as the core checklist before you worry about the smaller details.

• SHL. One of the most widely used providers globally. Offers numerical, verbal, and logical reasoning ability tests alongside the Occupational Personality Questionnaire (OPQ), a personality assessment used heavily in UK and European corporate hiring. Practice material closely matching SHL formats is widely available.
• Hogan Assessments. Three tools: the Hogan Personality Inventory (normal-range personality), the Hogan Development Survey (derailers under stress), and the Motives, Values, and Preferences Inventory (work environment preferences). Used primarily for senior hiring and leadership development assessments.
• Saville Assessment Wave. A comprehensive personality questionnaire used frequently in UK-based hiring, particularly for graduate and early career programs. Known for its length and depth.
• Korn Ferry Assessment of Leadership Potential (KFALP). Used for mid- to senior-level leadership hiring. Combines cognitive, personality, and learning agility assessment.
• Pymetrics. Uses neuroscience-based games rather than traditional question-and-answer formats to assess cognitive and emotional traits. Used by some major tech and consulting firms as an alternative to traditional aptitude testing.

Knowing which provider an employer uses helps you target your preparation. Most providers publish information about what their tests measure, and third-party practice materials are available for SHL, Korn Ferry, and other major providers.

The points below give you the most practical starting place for applying this concept well in a real interview. Use them as the core checklist before you worry about the smaller details.

• For ability tests: practice under timed conditions to improve speed and accuracy. There is a right answer to every question, and the test is measuring both how many you answer and how accurately you answer them. See the aptitude test page for specific preparation guidance by question type.
• For personality tests: answer honestly rather than strategically. Well-designed personality assessments include validity scales that detect inconsistent or socially desirable response patterns. Candidates who try to present an idealized version of themselves often produce a profile that flags as unreliable, which is more harmful than an honest profile that does not match the role.
• Read the instructions for each section carefully. The most common errors in psychometric tests come from misreading what a question is asking, not from inability to answer it correctly. This is particularly true in verbal reasoning, where the "based only on the passage" rule trips many candidates who are confident readers.
• Take your time on personality sections even when there is no time limit. Many personality questionnaires do not impose a time limit. Taking time to genuinely reflect on each item produces a more accurate and consistent profile than rushing through.

The fundamental insight is that personality tests are looking for fit, not a performance to score you on. A profile that accurately represents your working style, even if it is not a perfect match for a specific role, is more useful to both you and the employer than a manufactured profile that creates a false match.
