Personality assessments are used by companies during the hiring process to gain insights into how well a candidate will fit into the company culture, perform in a potential position, and stay motivated and inspired. These assessments provide objective data that enables better decision-making and helps employers evaluate candidates to reduce the potential for costly turnover and low productivity. By understanding employees as individuals and as a team, personality tests can increase productivity, teamwork, and communication, leading to a happier and more profitable business. However, the use of personality assessments in hiring decisions is a controversial topic, and it is important to use the proper assessment, apply insights correctly, and consider potential biases to ensure ethical use.
