Studies have just revealed that 60% of workers are coming across personality tests during their hiring process. Starting from the 1980’s these tools promised a “scientific” solution to costly hiring errors. With this wide adoption, the question comes up;

Are personality tests good for hiring?

Yes, personality tests can be perfect for hiring if properly utilized, if the correct model is used, which is backed by science and research. Moreover, pairing personality tests with interviews and skill tests is the way to move forward. This increases the accuracy of the right hire.

In this guide, we will cover all the factors you need to consider before concluding whether personality tests are good for hiring. Furthermore, we will discuss the pros and cons so you can judge for yourself better. Let’s dive in! 

The Rise of Personality Tests in Hiring

Personality tests are assessments or checklists meant to assess qualities such as work style, problem-solving ability, or social skills. 

For companies over the past few decades, they have become an essential tool. But why is that?

Why Did Companies Start Using Personality Tests in Hiring?

In the 1980s and 1990s, companies looked to go beyond resumes and gut feelings. Moreover, in hopes that these tests may forecast two things:

  • Whether an applicant would fit the position
  • If they fit the team’s culture

Overall, reducing recruiting errors with “science” seemed like a straightforward concept. 

As a result, companies started to adopt personality tests in hiring.

Companies wanted quicker ways of screening candidates as positions become more competitive with time. Well, this is where personality tests hopped in as a saviour. 

Personality tests provided a short fix, sorting hundreds of applicants into “ideal” or “not ideal” categories. 

Over 60% of companies today use them, particularly for positions where leadership or teamwork counts.

These tests save time and cut bias, which makes employers pleased. Critics counter that they are a lazy replacement for actual human judgment. 

While some businesses claim that the outcomes are fair, others worry that they ignore excellent individuals who deviate from a “type.”

Are Personality Tests Good for Hiring? 

The reason behind companies adopting personality tests is clear now. But are personality tests good for hiring? Is it actually useful and helps companies find talent, or is it just a lazy way for companies? 

In short, yes, personality is good for hiring. It adds value when used thoughtfully, not as a shortcut, but as part of a bigger strategy. 

Furthermore, personality tests are not a standalone solution and nor should they be. Instead, they should be paired with interviews and other skill tests. The success of hires relies on how and when they are used. 

Why Are Personality Tests Good for Hiring? 5 Key Reasons

1. Perfect Job Fit

The purpose of personality tests is to match a candidate’s natural skills with the requirements of a job. 

Detail-oriented jobs like coding or accounting benefit from high conscientiousness numbers, while sales jobs value outgoingness and toughness. 

Having emotional stability and awareness helps leaders understand the traits that indicate a person’s ability to solve conflicts.

Employers can use these pieces of information to find candidates who are a perfect fit for the job.

2. Reducing Bias

In traditional interviews, candidates who are charming or who have personal ties are often given greater importance. These tests get rid of “gut feelings” by focusing on facts. 

It’s an excellent opportunity for shy people, neurodiverse people, or candidates who aren’t as polished but are talented.

3. Lowering Turnover

Personality tests cut down on costly mismatches by ruling out people who might have trouble with the job requirements or the company’s culture. 

When employees are good at their jobs, they tend to stay longer. As a result, it saves tons of company money.

4. Identifying Leadership Potential

Soft skills like empathy and decisiveness are critical for managers. Personality tests enable employers to find leaders who will lead the team. 

Furthermore, it also helps in finding potential leaders who can shine with some training.

5. Balancing Team Dynamics

Tests keep teams from having too many people of a certain personality type. For example, a team where everyone is a risk-taker is a difficult environment to succeed as a company.

Pairing personality tests helps pair people with traits that work well together. 

For example, a candidate who has a trait such as creativity can be paired with someone who has the execution soft skill. As a result, they complement each other.

The Reality of Personality Tests in Hiring

Modern personality assessments like SAJOKI use verified frameworks such as the DISC, MBTI, and the Big Five. They offer employers unique insights that traditional hiring methods often miss. 

However, personality tests are not a standalone solution and nor should they be. Instead, they should be paired with interviews and other skill tests. 

The secret is applying the correct tool for the role. Furthermore, using research and science-backed personality is key for accurate results. 

Employers who pick scientifically established tools avoid gimmicks and get information on how applicants might develop into a position. This is a game changer for companies. 

The Verdict: A Tool, Not a Solution

To conclude, personality tests can be an excellent option for hiring. Though they are not magic either, personality tests are not ineffective. The success of hires relies on how and when they are used. 

For positions like customer service or leadership, where soft skills are very vital, they can provide insightful analysis. 

For instance, a manager’s capacity for handling conflict or communicating might match characteristics like emotional stability or agreeableness.

On the other hand, these tests shouldn’t be the only dependable factor for good hires, as already mentioned. While personality tests give a small picture, combining them with others draws the full picture of a candidate.

Lastly, the biggest risk lies in overconfidence. Employers who treat these test results as the bible often miss red flags or diamond-in-the-rough candidates.

The Pros and Cons of Personality Tests in Hiring

Now that you are aware whether are personality tests good for hiring or not, we can jump into the pros and cons section. 

Everything has its dominance and limitations, and it is true for personality tests as well. 

While personality tests can be a good option for hiring, knowing about their strong points and limitations will help you measure whether to implement them.  Let’s check out the pros and cons before we dive in deep with it.

Pros Cons
Reduces bias by prioritizing objective traits over “gut feelings.” Risk of accidentally screening out qualified candidates due to rigid criteria.
Builds teams aligned with shared values and culture. May foster a “cloned” workforce, stifling diversity and innovation.
Predicts success in roles requiring soft skills. Candidates can manipulate tests to appear more desirable.
Streamlines high-volume hiring for roles like retail or hospitality. Privacy concerns around handling sensitive candidate data.

Now, let’s get into the details. 

The Pros of Personality Tests

Here are the areas where personality tests truly shine;

1. Reducing Bias By Avoiding Gut Feelings

Candidates that are charming, have interests with the hiring manager, or mirror the interviewer’s personality often find bias in the decision. 

Personality assessments change this by emphasizing attributes instead of charisma.

For example, a quiet but detail-oriented introvert might fail a casual interview but ace a test showing high conscientiousness. 

With personality tests, employers eliminate quick decisions and give underappreciated prospects a fair shot. This is done by including objective data in the process.

2. Building Teams with Shared Values

“Culture fit” is not about selecting employees based on their enjoyment of identical TV shows. It is about harmonizing values and actions. 

Startups that give flexibility first priority, for example, may utilize tests to find individuals with strong flexibility and curiosity. These traits enable quick pivots, which are essential in startups.

According to a Deloitte survey, 94% of executives say that success depends on workplace culture. Furthermore, assessments help to define what that culture looks like in practice.

Overall, clear corporate values combined with personality testing produce teams that function together. 

3. Predicting Success in High-Stakes Roles

Personality tests excel in professions where soft skills either make or break outcomes. For example;

    • Leadership: Emotional stability and empathy help to forecast how effectively managers handle mentoring teams or conflict.
    • Sales: Traits connected to extroversion, resilience, and optimism help salespeople recover from rejection.
    • Healthcare: For nurses or therapists, empathy and conscientiousness are usually greater indicators than technical ability by itself.

These roles depend on behavior rather than on knowledge. 

Since personality tests are great in finding these key traits, roles that require specific soft skills must be tested with personality tests.

4. Streamlining High-Volume Hiring

For businesses like retail, hospitality, or call centers where hiring hundreds of seasonal workers is typical, personality tests save time. They filter candidates likely to struggle with essential job requirements, therefore automating the first screening stage.

For example, a retail job needing regular client contact might give extroversion and agreeableness top priority. Personality tests can highlight candidates who would rather work alone. Thus, allowing HR to concentrate on those fit for the responsibilities of the position.

The Cons of Personality Tests

Let’s check out the drawbacks that you might come across with personality tests.

1. Accidental Unfair Screening

Personality exams might unintentionally wipe out talented applicants. 

For example, introverted applicants might score poorly on assessments that prioritize extroversion. However, the job role requires intense concentration, such as data processing or coding.

On the other hand, people who are on the autistic spectrum might score low on team collaboration where whereas the role calls for detail-oriented people. 

Companies should thus concentrate on qualities directly related to the job in order to solve this. 

2. Hiring Clones, Not Innovators

The term “cultural fit” has become very popular in the modern era. Meaning, hiring candidates who share the same interests and values.

This results in a cloned office environment where fresh ideas find difficulty in flourishing. 

On the other side, studies demonstrate that diverse teams solve issues faster and generate greater innovation. 

Rather than looking for carbon copies of present staff, companies should give other matters, such as creativity, a top priority.

3. Some Know How to Outplay the Test

Some contenders just knows how these tests work and may figure out ways to outplay the test itself. 

They’ll answer questions to appear optimistic, collaborative, or assertive, traits employers love, but lack the actual skills to do the job.

To avoid this, pair personality tests with practical assessments. This will help you understand the candidate more than only utilizing personality tests.

4. Privacy Concerns

When candidates take these tests, they provide extremely private data. However, only a few employers explain how that information is used. Is that kept safely?

Without transparency, companies risk violating trust or even privacy laws like GDPR.

This is why sticking with reliable test providers like SAJOKI is vital to ensure the data is properly used. Furthermore, safe from hackers.

3 Common Mistakes to Avoid When Using a Personality Test For Hiring

Personality tests can backfire and lead to ineffective hires instant if its not used properly. Here’s how to sidestep the biggest pitfalls:

1. Using a One-Size-Fits-All Test

Not all roles need the same traits. A test designed for extroverted salespeople won’t work for introverted coders.

Solution: Fit the test to the job. For example, use empathy metrics for nurses and problem-solving metrics for coders.

2. Ignoring Skills and Experience

A charismatic candidate might ace a personality test but lack technical skills. Personality tests often miss the skills and experience gathered by the candidate.

Solution: Pair tests with skills assessments, such as a coding test.

3. Keeping Candidates in the Dark

Companies often don’t explain themselves for utilizing personality tests for this role. Furthermore, not even clearing what these tests are. People dislike taking tests they don’t understand.

Solution: Explain why you’re using the test and how results impact hiring.

FAQ

Can candidates retake a personality test if they feel their results don’t reflect them?

Most tests don’t allow retakes, as rehearsed answers can skew results. However, employers should offer feedback and clarify that tests are just one part of the process.

Are personality tests worth the cost for small businesses?

It depends. For roles where soft skills are critical, personality tests can be an excellent tool for better hires.

How often should we update or change our personality assessments?

You should update or change personality tests every 1 to 2 years. Company goals evolve, and traits that mattered for a startup’s “hustle culture” may not suit a scaling team needing process-oriented hires.

Conclusion

To conclude, we hope you got your answer to whether are personality tests good for hiring. Personality tests aren’t magic, but simply a tool that can enhance your hiring process for better hires if used correctly. Yes, they reduce bias and streamline hiring, but their power lies in balance.

For employers, the future of hiring isn’t about choosing between resumes or quizzes. It’s about blending data with humanity. Audit your process, prioritize fairness, and remember: a test score is a snapshot, not the whole story.
