This book analyzes the recruitment and selection of leaders in the public service in Minas Gerais through the Transform Minas program, focusing on the search for professionalization. To this end, it uses a case study of the process of recruitment and selection of regional directors of SEDESE. Since its formation, Brazil has suffered the consequences of clientelism, so that there is a domination of the public space for private interests. Thus, the goal is to establish a culture of impersonality, through the professionalization of public service, a process that is closely related to the recruitment and selection area. In this way, the present work seeks to analyze the effects that the Transform Minas program has had on the professionalization of the recruitment and selection process in the public service of Minas Gerais. In order to do this, a bibliographic review of the themes of clientelism, recruitment and selection and the professionalization of the civil service is used. The methodology involves bibliographic, documental and field research, by means of a questionnaire and interviews with strategic managers and directors who have gone through the program.
