Research supported by institutional theory contributes to organizational studies because they insert variables such as shared values, search for legitimacy, and isomorphism in the analysis of relationships between organizations and between organizations and the environment. In this context, this article aims to analyze the stages of institutionalization in consulting companies providing services in the recruitment and selection of people (R&S). A qualitative-descriptive study was performed with six recruitment and selection consultancies located in Sergipe. The results demonstrated the administrative functioning of organizations about the stages of institutionalization, revealing an institutional scenario for these service providers, besides highlighting the main obstacles to the sedimentation of the companies analyzed.
