This multiple case study explored the experiences that business alumni had in competency-based leadership programs during their time as business undergraduate students in two universities, one in Mexico and the other in the United States. Methodological triangulation was addressed by collecting data from several sources and through different methods. Seven participants from Mexico and six from the United States who graduated between 2017-2021 from diverse business bachelor's programs, and have been in leadership positions in the workplace, were interviewed. The strategies of pursuing members' meanings, coding, and analytic memos were employed for analyzing single cases. Also, I used a model of leadership competencies development as an a posteriori theoretical framework. For cross-case analysis, I employed the strategies of coding, similarity, and analytic memos. Five findings from the Mexican data and four from the American data are discussed within their institutional contexts. Implications for research, theory, and practice are included.
