Personality is more than just a buzzword; it’s a key component in determining how well a person will adapt, perform, and grow within your organization.
For CEOs, HR professionals, and recruitment strategists, understanding personality at a deeper level can help you build cohesive teams, reduce turnover, and create an environment where everyone can thrive.
One of the most renowned frameworks for examining personality in both academic research and corporate settings is the Big Five Personality Traits.
In this blog, we’ll explore what the big five personality traits test is all about, how it works, and how you can incorporate it into your hiring process.
What Is the Big Five Personality Traits Test?
The Big Five model—often summarized by the acronym OCEAN—is based on five core dimensions of personality:
- Openness to Experience – Creativity, curiosity, and a preference for variety.
- Conscientiousness – Organization, dependability, and goal orientation.
- Extraversion – Sociability, assertiveness, and enthusiasm.
- Agreeableness – Cooperation, empathy, and willingness to collaborate.
- Neuroticism (Emotional Stability) – Resilience, calmness under stress, and overall emotional balance.
The test measures how individuals rank on these five factors, providing valuable insight into typical behaviors and preferences—such as whether someone is naturally collaborative, detail-oriented, or resilient under pressure.
Because of its strong scientific foundation, the Big Five has long been a popular tool in academic psychology and organizational behavior, making it a powerful addition to your personality assessment toolkit.
Why the Big Five Personality Traits Matter in the Workplace
1. Predicting Job Performance and Fit
Certain jobs require a higher degree of conscientiousness, such as those involving project management or quality assurance. Meanwhile, roles that demand strong interpersonal skills may benefit from higher levels of agreeableness and extraversion. By pinpointing which Big Five traits are most valuable for a given role, you can hone in on candidates who are naturally inclined to excel.
2. Building Strong Teams
Teams often function best when members bring diverse personality traits to the table. A blend of openness and conscientiousness, for example, might foster both innovation and task completion. An environment with balanced traits may help reduce conflict and optimize collaboration.
Tip from 20+ years of experience: When building a sales team, don’t overlook the importance of emotional stability (neuroticism). A level-headed sales rep often manages stress better and maintains strong customer relationships.

3. Enhancing Employee Engagement and Retention
When employees are in roles that align well with their personality, they tend to feel more engaged, satisfied, and loyal. This can reduce turnover costs and yield more consistent performance across the board. For instance, a highly openness-oriented person might quickly become restless in repetitive tasks but flourish in research or creative problem-solving roles.
Is the Big Five Model Reliable?
Yes, the Big Five is widely regarded as one of the most reliable and valid frameworks according to research for measuring personality, which explains its popularity in organizational behavior research and HR practices. However, not all Big Five tests are created equal, so it’s important to ensure you’re using a reputable version.

Administering and Interpreting the Big Five Personality Traits Test
1. Choose a Validated Assessment Tool
Make sure the assessment provider has documented reliability and validity evidence. Free online quizzes can be tempting, but as a business, it’s vital to use robust, scientifically validated solutions—particularly if you plan to make employment decisions based on the results.
We cover some of the most widely used assessments (including the Big Five) in our list of Popular Personality Tests for Effective Pre-Employment Assessment.
2. Integrate the Test Into Your Hiring Process
Consider at which stage you want to introduce the assessment. Some companies prefer to administer it after an initial phone screening to narrow down a shortlist. Others wait until the final stages, so they can compare results among top contenders. The key is to ensure the test results are combined with interviews and other data, creating a more comprehensive talent profile.
For a quick but insightful approach, you might explore our Short Personality Test for Candidates. It provides a snapshot of an applicant’s traits, helping you gauge fit before deeper assessments.
3. Interpret Results Within Context
A high score on openness could indicate creativity but might be less critical for a position demanding strict adherence to protocols. Similarly, a lower agreeableness might be acceptable in roles that require tough negotiation or conflict resolution skills. Always contextualize scores relative to the role’s demands and your organizational culture.

Big Five in the Hiring Pipeline: Practical Tips
- Define the Traits You Need: Not every role requires the same mix. Identify which traits are critical for success in each position (e.g., high conscientiousness for data-oriented jobs).
- Pair It With Other Assessments: The Big Five is powerful, but combining it with other validated tools—like cognitive or technical tests—gives a more holistic view of a candidate. Our Pre Employment Personality Tests offer a comprehensive suite of assessments that can complement the Big Five results.
- Communicate Why You’re Using It: Being transparent about why and how you use personality tests can help candidates feel comfortable and engaged, leading to more accurate results.
- Use Results as a Guide, Not an Absolute: Personality testing should inform, not dictate, hiring decisions. Combine test outcomes with in-depth interviews, references, and job simulations to minimize bias.
