This research provides insights into how to enhance recruitment process outsourcing (RPO) project outcomes by improving partnerships with the RPO provider. We posit that knowledge sharing and top management support enhance partnership quality by increasing both parties’ mutual dependence and commitment to the relationship. We conducted a survey of 150 RPO projects. The results demonstrate the effectiveness of knowledge sharing and top management support for enhancing partnership, leading to enhanced RPO project outcomes (i.e., recommended candidates’ person-job fit). Theoretical and practical implications of the results are discussed.
