People used to believe that big life events, like having a baby or getting a serious illness, changed a person's character or personality. However, recent studies show that personality is actually very stable and not shaped by these events. People tend to have a fixed personality throughout their lives, which is why understanding their traits is valuable. This is particularly important for employers who want to learn about their employees’ personalities.

What is a personality test?

Personality tests are designed to reveal the character of an individual, or, in the case of business, of a future employee. This is because a person's personality plays a major role in future employment behavior. A good personality test may give employers insight into the personality profile of the candidate, helping them decide whether someone is the right fit for the job. The test also saves an immense amount of time, effort, and money.

Personality tests continue to gain prominence. Their popularity has actually increased by almost 63% since 2001. Virtually every major company is taking advantage of the valuable insight bestowed by administering such tests.

Personality is stable

Personality tends to be stable—it doesn’t change overnight. That’s exactly why tools like the 4 color personality test are so valuable.The insights you gain from a personality test usually stay relevant for years. In most cases, you only need to take it once to get a clear picture of how someone naturally works, communicates, and interacts with others. For companies, that’s incredibly useful. It helps you quickly see if someone’s a good fit for a role, a team, or even ready for a new challenge.

The Big Five personality test

The most widely used personality test by employers is the Big Five personality test. It was developed using the theory that human personality is made up of 5 character traits (hence, the Big Five).

Together, these traits form the main component of the candidate's personality. The Big Five is a very valid and reliable instrument that, by using innovative techniques, can also detect socially desirable responses and dishonest answers.
