What is a Personality Test?

These tests are designed to elicit information about someone's thoughts, opinions, traits, motivations, behavioral tendencies, and values.

Frequently Asked Questions(FAQs)

A personality assessment test is commonly used in the pre-employment assessment process to assess human personality constructs. Hence, a psychometric test for personality can help recruiters understand the characteristic pattern of behaviors, thoughts, and beliefs that candidates reveal in different situations. Simply put, a personality assessment is a tool employers use to identify candidates with personality traits best suited for a particular job/role. In addition, the personality assessment process can provide information about how the specific aspects of a candidate's personality will determine their workplace behavior.

As the name suggests, an employment personality test is designed to understand individuals' personality traits, behavioral tendencies, and preferences to determine whether they fit a particular role. For example, a leadership personality test interprets a candidate's competencies required for a leadership role. The personality traits test helps determine their work ethic, preferred working environment, inclination to work and how likely they are to efficiently address relevant work-related needs and issues.

Personality testing in the workplace is of paramount importance, whether it's about providing vital insights into hiring decisions or furnishing objective insights into employee training, development, career advancement, etc. Personality tests can help assess the complete spectrum of personality traits, from positive to dark characteristics, making them ideal tools for selection and organizational development. Personality tests are a surefire way to assess critical behavioral competencies for all roles across industries.

Personality tests expose candidates to a wide range of questions that tag them into specific 'types' based on their preferences, behavioral patterns, attitudes, etc. These tests provide a comprehensive view of a prospective hire that helps to understand where that candidate might be best placed in a company, how to address skill gaps in different teams, what leadership style senior executives might adopt to drive high team performance, etc. Therefore, the main objective of personality tests is to furnish actionable insights that help in making informed talent decisions.

Personality assessments can be classified into two types: trait-based personality assessments and type-based personality assessments. The Big Five personality test model is a popular trait-focused personality assessment model. Most of the modern personality assessments are based on this model. On the other hand, the Myers-Briggs Type Indicator (MBTI) is a widely known type-focused personality assessment model commonly employed across many industries.
