John L. Holland was an American Psychologist that dedicated his professional life to studying personality and the workplace. As a result he created what are now known as the Holland Codes or the Holland Occupational Themes (RIASEC), a set of six major personality types that can indicate a person’s general interests, work habits and lifestyle choices. Once the codes were published in 1958 they became a popular tool in career counseling and guidance, and are still used nowadays. The US Department of Labor's Employment and Training Administration has been using RIASEC model (https://www.onetonline.org/)

The personality traits are incredibly important when selecting a job because they will help determine whether someone will thrive in a position. A job is essentially, according to the theory an extension of your personality.
