The evolution of personnel selection systems has been driven by technological advances and changes in the needs of organizations, referring to the set of processes and tools used by an organization to evaluate and select the most suitable applicants to fill a position within the company, in order to ensure that people with the skills, knowledge and competencies necessary to perform the responsibilities and functions associated with the position are hired. It is therefore proposed to implement a personnel selection system, which will help optimize the recruitment and selection process using the competency model and the selection algorithm to choose the best candidates according to the selection criteria established for each job position, resulting in the best candidates for the position with the qualities for which they were chosen.
