Personality tests for hiring: how to use them and 4 examples.

More and more companies add a personality assessment to their recruitment process, and more and more candidates expect one. Used well, personality tests for hiring give recruiters something a CV, a LinkedIn profile and a first interview cannot: a consistent, comparable read on how a candidate tends to work. Used badly, they put people in boxes and expose the employer to legal risk.

This guide explains what a pre-employment personality test is, why employers use personality tests for hiring, how to use them in your recruitment process without the common mistakes, and the four personality tests most often used for hiring, with example questions for each.

‍

What is a pre-employment personality test?

A pre-employment personality test is a standardised questionnaire that job applicants complete before a hiring decision, designed to measure stable traits such as conscientiousness, sociability, resilience and openness to new ways of working. Every candidate answers the same items, and the results are scored against the same scale, so profiles can be compared directly.

Unlike a skills or cognitive test, an employment personality test has no right or wrong answers and no pass mark. It does not measure whether a candidate can do the job. It measures how they are likely to approach it: how they respond to pressure, how they prefer to work with others, how much structure they need, how carefully they handle detail. That is why a personality assessment for hiring is almost always used alongside a measure of ability, not instead of one.

The terms overlap in practice. "Personality test", "personality assessment", "employment personality assessment" and "work style assessment" all describe the same family of tools. Vendors tend to say "assessment"; candidates and hiring managers tend to say "test".

Why do employers use personality tests for hiring?

Recruiters have always judged personality, in the first ninety seconds of an interview, from a handshake and a CV layout. A personality assessment does not add a new judgement to the process. It replaces an unstructured one with a structured one. Three reasons employers use them:

Predicting job performance

Decades of selection research show that certain personality traits predict performance in almost every job, with conscientiousness the most consistent, and that others predict performance in specific roles, such as extraversion in sales and management. The same research is clear that personality measures work best combined with structured interviews and work samples rather than on their own.

In plain terms: a personality assessment tells you something real about how a candidate will perform, and it tells you most when it is one input among several.

Reducing bias and supporting diversity

Gut-feel hiring rewards candidates who resemble the interviewer. A standardised employment personality assessment gives every applicant the same questions, scored the same way, before anyone has seen a name, a photo or a university. That does not remove bias from the process, but it removes it from one step, and it gives the recruiter an objective data point to weigh against the impression formed in the room.

Checking fit with the role and the team

This is the reason most companies give, and the one most often misunderstood. Fit does not mean hiring people who resemble the current team. It means matching a candidate's working preferences to what the role actually demands: sustained detail work, constant customer contact, ambiguity, autonomy, tight deadlines. Personality is more stable than behaviour, so a match confirmed by a personality assessment at the point of hiring tends to hold. Employees whose preferences match the daily reality of the job stay longer and need less managing.

How to use personality tests in recruitment

Personality testing for recruitment works when it is designed into the process. Four rules.

Choose a test that matches the job

The personality assessment and its questions must be relevant to the role, not just to the company. Before choosing a test, write down what the job requires in behavioural terms:

• Which two or three traits genuinely separate strong performers from weak ones in this role, such as comfort with ambiguity, persistence under rejection, or precision under time pressure.
• Which working style the team is missing and would benefit from.
• Which traits are irrelevant to performance and should be ignored, however tempting they are to score.

That list tells you which of the tests below to use, and it is also the record you will need if anyone asks why the test is job-related. Modern AI assessment software lets you assemble a role-specific assessment from validated personality and skills tests in minutes, rather than buying one generic test for every job.

Decide when to test

There is no single right moment for a pre-employment personality test. The three common placements:

• At the screening stage, alongside other tests. Best for high-volume hiring, where a short personality assessment combined with a skills test does the first sift consistently.
• After CV selection, before the interview. The most common placement. Results arrive before the interviewer meets the candidate and turn a generic conversation into a targeted one.
• At the shortlist stage. Used to compare the final candidates on role fit when ability is roughly equal.

Whichever you choose, be conscious of the candidate's time. A succession of long personality tests drives good applicants to employers who ask less of them before an offer.

Use personality tests in the interview process

The most valuable use of a personality test in the interview process is as a script for the interview itself. A profile that shows low comfort with ambiguity, for a role full of it, is not a rejection. It is a question: "Tell me about a time you had to act before the picture was clear." A profile that flags very high agreeableness in a role that requires saying no to customers deserves the same treatment.

Interviewing this way tests whether the personality test result holds up against real examples, and gives the candidate a fair chance to explain a result rather than being silently screened out by it.

Interpret results, do not label people

Personality tests for hiring provide data, and data needs reading.

• Contextualise the result. A profile indicates the environments in which someone is likely to thrive, not a verdict on whether they can do the job.
• Leave room for nuance. Scores sit on a scale; nobody is purely one type.
• Review the test's track record. After a year, compare personality test results at hire with performance and retention. If the test is not predicting anything, change it.
• Never use a personality assessment as the sole reason for rejecting a candidate.

Keep it fair and legal

In most jurisdictions the rule is the same: a selection test must be job-related, applied consistently to all candidates, and must not screen out protected groups at a higher rate without a justified business reason. Two cautions specific to personality assessments. First, instruments designed to diagnose psychological conditions can count as medical examinations under disability law and should not be used for selection. Second, where an algorithm scores or ranks candidates, transparency and bias-audit obligations increasingly apply. Choose a personality test built for employment use, keep the job analysis on file, and review outcomes by demographic group.

Can you trust personality tests for hiring?

Yes, within limits. Two objections come up most often.

Candidates can fake them. Some try. There are no right answers, which encourages honesty, but a candidate who wants a sales role can guess that "I enjoy meeting new people" is the answer to give. Well-built tests reduce this with consistency checks and forced-choice formats, where every option is equally attractive. The stronger defence is the interview: corroborate the profile against real examples, and a faked result usually shows.

They put people in boxes. Type-based tests do. Trait-based personality assessments, which score each dimension on a scale, do not, and they are the ones with the research behind them.

The honest summary is that personality tests for hiring are a reliable measure of one thing, working style, and an unreliable measure of everything else. Pair them with a skills or cognitive test that measures whether the candidate can do the work. Our guide to the types of pre-employment assessment covers the options.

The 4 best personality tests for hiring, with examples

Below are the four personality tests most often used for hiring, what each measures, who it suits, and an example item.

1. The Big Five test

Also called the Five Factor Model, the Big Five is the most researched personality framework in occupational psychology and the basis of most modern employment personality assessments.

How it works. Candidates rate themselves against a series of statements, usually between 40 and 60, on a scale from strongly disagree to strongly agree. Rather than assigning a type, the test returns a score on each of five traits:

• Openness: curiosity and comfort with new ideas versus preference for the familiar.
• Conscientiousness: organisation, reliability and follow-through versus a looser, more improvised approach.
• Extraversion: energy drawn from social interaction versus from working alone.
• Agreeableness: cooperation and concern for others versus competitiveness and directness.
• Emotional stability (the reverse of neuroticism): steadiness under stress versus sensitivity to it.

Example item: "I keep my commitments even when it is inconvenient." Strongly disagree to strongly agree.

Who it is for. Almost any employer. Conscientiousness predicts performance across roles, so the Big Five is the default choice for a general pre-employment personality assessment. It is short, easy to complete online and produces results a hiring manager can read without training.

2. The Dark Side test

Most personality assessments measure how someone behaves at their best. Dark side tests, sometimes called derailer assessments, measure how they behave under pressure and ambiguity, when the rules are unclear and nobody is watching.

How it works. The candidate is presented with situations that have an obviously virtuous outcome, an obviously harmful one, and a lot of grey in between, and asked how they would act. The result is not a good or bad score. It reveals the strength of a candidate's judgement and the tendencies that could derail them: excessive caution, excessive boldness, bending rules to hit a target.

Example item: "A deadline is at risk. Meeting it would mean skipping a compliance check nobody is likely to notice. What do you do?"

Who it is for. Roles with real decision-making authority, high-pressure environments, and positions involving money, safety or sensitive data. It supplements a trait-based personality test rather than replacing one.

3. The DISC test

DISC places a candidate on four behavioural scales rather than in a single box, and is one of the most widely used personality tests in recruitment for customer-facing and collaborative roles.

How it works. Candidates choose the statements that describe them most and least from sets of four. Each letter is a behavioural style:

• D for Dominance: direct, decisive, comfortable taking charge and pushing projects forward.
• I for Influence: persuasive, sociable, motivated by relationships and recognition. Common in strong salespeople.
• S for Steadiness: patient, dependable, a stabilising presence in a team that takes risks.
• C for Conscientiousness (Compliance in older versions): precise, analytical, focused on standards and accuracy.

Example item: Choose the statement most like you and least like you: "I take charge in a group", "I win people over", "I keep things steady", "I get the details right."

Who it is for. Employers with clear job descriptions who want to match working style to daily duties. People perform better and stay longer in roles that suit their style, so DISC is useful for long-term hiring decisions and for building teams whose styles complement each other.

4. The 16 Personality Types test

The best-known personality framework outside HR, and included here because candidates and managers ask about it. It sorts people into one of 16 types across four dimensions:

• Extraversion (E) or Introversion (I)
• Sensing (S) or Intuition (N)
• Thinking (T) or Feeling (F)
• Judging (J) or Perceiving (P)

Example item: "At a party, you: (a) talk to many people, including strangers, or (b) talk to a few people you know."

Who it is for. Team development, onboarding and communication, not selection. The Myers-Briggs Company's own code of ethics states that the MBTI should not be used to screen job applicants, and the research supports that: type-based results are not stable enough over time or predictive enough of performance to justify a hiring decision. Use it after the hire to help a new team understand each other, and use one of the three tests above to make the decision.

Example personality test questions for employment

Employers often ask what a personality test for a job actually looks like. Most employment personality assessments use one of three item formats:

• Rating statements. "I prefer to plan my day in detail." Strongly disagree to strongly agree. Used by the Big Five and most trait-based tests.
• Forced choice. "Which describes you better: I speak up first in meetings, or I prefer to hear others before I contribute?" Harder to fake, because neither option is obviously right.
• Situational judgement. "A colleague takes credit for your work in front of your manager. Rank these four responses from most to least like you." Measures judgement in a realistic work context.

A well-designed pre-employment personality test takes 10 to 20 minutes, mixes formats, and includes a few consistency checks that ask the same thing in different words.

Frequently asked questions

What is the best personality test for hiring?

For most roles, a Big Five test, because conscientiousness predicts performance across almost every job. Add a dark side or situational test for roles with real decision-making risk, and DISC where working style and team dynamics matter most.

Can a candidate fail a personality test for a job?

No. There is no pass mark. Employers compare a candidate's profile to the demands of the role, and a profile that suits one job poorly may suit another well.

Are personality tests for employment legal?

Yes, provided the test is job-related, applied consistently to all candidates, does not screen out protected groups without justification, and is not a clinical instrument designed to diagnose conditions.

How long does a pre-employment personality test take?

Between 10 and 20 minutes for a good one. Longer tests lose candidates and rarely add predictive value.

Final thoughts

Candidates may pass every skills test and still struggle with the behavioural demands of a job. Personality tests for hiring measure that second dimension, consistently for every applicant rather than in the first minute of an interview. Used as one input among several, matched to the role and read with care, a pre-employment personality assessment helps you hire people who will do the job well and stay in it.
