A candidate interviews well, has the right experience, and looks strong on paper. Then six months later, the hire is struggling with pace, team dynamics or stakeholder pressure. That gap is exactly why employers ask what personality tests do employers use, and whether those tools genuinely improve hiring decisions.
The short answer is that employers do not usually rely on one single personality test. They use a range of psychometric assessments designed to measure behavioural style, workplace preferences, interpersonal tendencies and likely fit with the demands of a role. The better question is not just which tests are used, but what each one is designed to predict and how safely it should be interpreted.
What personality tests do employers use in recruitment?
In practice, most employers use personality assessments that fall into a few broad categories. Some are built around normal workplace behaviour, such as how a person communicates, plans, responds to pressure or works with others. Others are designed to identify potential derailers, risk factors or leadership style. A smaller group is marketed as culture-fit or team-fit tools.
Among the best-known names in the market are the Big Five-based assessments, DISC, the 16PF, Hogan assessments, SHL occupational personality questionnaires and Myers-Briggs style tools. Not all of these are equal in a hiring context.
Big Five assessments are widely respected because they are grounded in a strong body of psychological research. They typically measure traits such as conscientiousness, emotional stability, extraversion, agreeableness and openness to experience. For employers, the value is not in putting candidates into a simple type, but in understanding job-relevant tendencies. High conscientiousness, for example, often matters in roles that require reliability, structure and attention to detail.
DISC is also commonly used, particularly in commercial environments. It looks at behavioural preferences across dominance, influence, steadiness and conscientiousness. Employers often like DISC because it is easy to understand and simple to discuss with managers. The trade-off is that it is generally more useful for communication and team development than for making high-stakes hiring decisions on its own.
The 16PF has a longer history in occupational assessment and provides a broader personality profile. It can be useful when organisations want more depth than a lighter-touch behavioural tool provides. It is often applied in professional, technical and leadership hiring where a more detailed view of interpersonal style, reasoning and resilience is helpful.
Hogan assessments are widely used for management and executive roles. They typically examine everyday strengths, potential derailers under stress and key drivers or values. That combination can be especially useful in leadership recruitment, where success depends not just on capability but on judgement, reputation and behaviour under pressure.
SHL occupational personality tools are another common option in larger organisations and enterprise recruitment programs. They are designed for workplace use and often sit alongside cognitive ability testing and structured reporting. This makes them practical for employers who need standardisation at scale.
Myers-Briggs style tools still appear in some workplaces, but they are better suited to development conversations than selection decisions. They can help people reflect on preferences, but they are not generally considered the strongest option for predicting job performance. For employers concerned with fairness, defensibility and evidence, that distinction matters.
Why employers use personality tests at all
Personality assessments are rarely about finding a perfect person. They are about reducing uncertainty. Interviews can be inconsistent, referees are often positive by default, and CVs say little about how someone is likely to behave when workloads rise or stakeholders push back.
A well-chosen personality test adds structure. It helps employers compare candidates on the same dimensions, identify areas to probe in interview, and spot patterns that may not be obvious from experience alone. For high-volume hiring, this can improve consistency. For leadership hiring, it can provide a more rounded picture of strengths and risks.
That said, personality testing has limits. It does not measure skill, motivation in a specific context, technical competence or cognitive capacity with enough precision to replace other methods. A candidate may have a collaborative style and still lack the judgement required for a complex role. Another may show lower sociability but perform exceptionally well in a specialist or analytical position.
This is why strong hiring processes treat personality assessment as one data point, not the entire decision.
Which personality tests are most useful for employers?
The most useful test depends on the job, the level of risk in the hire, and how the results will be used.
For frontline and mid-level roles, employers often need something practical, scalable and easy to interpret. In those cases, occupational personality questionnaires based on validated workplace traits tend to work better than highly theoretical models. The goal is to support shortlisting and interview quality without adding unnecessary complexity.
For graduate recruitment, customer-facing roles and large intake programs, employers usually value consistency and speed. Personality measures can help identify behavioural fit for service, teamwork, adaptability or compliance-heavy environments, but they work best when paired with cognitive ability tests and structured interview questions.
For executive and senior leadership appointments, deeper assessment is usually warranted. A senior hire can affect culture, risk, retention and performance across an entire function. In these cases, employers often use personality tools that examine both strengths and derailment risk, supported by psychologist interpretation.
For safety-sensitive, regulated or public-facing environments, defensibility matters as much as insight. Employers need assessments that are validated, relevant to the role and administered consistently. A popular tool is not automatically the right one.
What personality tests do employers use with other assessments?
The strongest recruitment processes combine personality testing with other evidence. This is where many employers get better results.
Cognitive ability testing often sits alongside personality because it measures something different. Personality can indicate how someone is likely to approach work. Cognitive testing can indicate how quickly they process information, solve problems and learn new material. Together, they offer a more complete picture.
Skills testing adds another layer by showing whether the candidate can actually perform relevant tasks. This is especially useful in administration, customer service, technical, finance and digital roles. A candidate may present as highly organised and dependable on a personality measure, but a skills assessment confirms whether they can apply that effectively.
Structured interviews remain essential. Good assessment results should sharpen interview questions, not replace them. If a report suggests a candidate may be highly independent, the interview can explore how they collaborate in matrixed environments. If a profile indicates lower tolerance for ambiguity, the interviewer can test suitability for fast-changing roles.
This combined approach is generally more predictive and more defensible than relying on personality testing alone.
Common mistakes employers make
One of the biggest mistakes is using a personality test because it is familiar, not because it is job-relevant. A tool that works well in team workshops may not be appropriate for selection.
Another is treating results as pass-fail. Personality profiles are not exam scores. Most traits exist on a spectrum, and the right range depends on the role. High assertiveness might help in sales leadership and create issues in a highly procedural support role. Lower sociability could be a concern in relationship management but irrelevant in back-office analysis.
A third mistake is overinterpreting reports without proper expertise. Many assessments generate polished outputs, but polished does not always mean simple. Employers need to understand what the tool measures, how reliable it is, and what conclusions can reasonably be drawn.
Poor candidate communication can also create friction. If applicants feel they are being labelled or filtered by a black-box test, trust drops quickly. Clear explanation matters. Candidates should understand why the assessment is being used, how it relates to the role and how it fits into the broader selection process.
How to choose the right assessment
Start with the role, not the test. What behaviours actually matter in performance? Does the job require persistence, customer focus, detail orientation, resilience, influence or comfort with routine? Once that is clear, it becomes much easier to choose an assessment with the right level of depth.
Then look at validity, reliability and practical usability. Can the tool stand up in a recruitment setting? Is it suitable for Australian employers and candidate populations? Can managers understand the results well enough to use them appropriately? Can the process scale when hiring volumes increase?
Finally, consider support. Even strong tools are easier to implement when there is guidance on benchmark selection, interpretation and integration with interviews and other assessments. This is where providers with occupational psychology expertise tend to add real value, particularly for organisations that need consistency across multiple roles or business units.
For employers asking what personality tests do employers use, the most useful answer is this: they use different tools for different hiring risks, but the best outcomes come from validated workplace assessments used as part of a broader, evidence-based process. Personality testing can improve shortlisting, sharpen interviews and reduce guesswork, provided it is matched to the role and interpreted with care. If your hiring process still leans heavily on instinct, adding the right assessment framework is often where better decisions start.
