Many workplaces in Vietnam, such as international non-government organisations (INGOs), where Vietnamese staff collaborate with people from different cultures, have become increasingly culturally diverse and interdisciplinary. This paper is based on the findings of broader qualitative research conducted between December 2010 and November 2012 that explored young Vietnamese graduates' experiences of working at the intersection of different cultural worlds in the context of development projects at INGOs in Vietnam. Interviewees were nineteen young Vietnamese graduates and six international directors or deputy directors. This paper discusses their experiences of working for INGOs. Young graduates developed intercultural communication skills, became empathetic with others, and reconciled disparate cultural practices. While helping local communities adapt to development projects, graduates harmoniously combined the cultural values and customs of both sides. They disseminated information, promoted mutual understanding, formed culturally relativistic attitudes, promoted cross-cultural empathy, spread international goodwill and reconciled disparate cultural practices, facilitated communication, and interacted with persons or groups of different cultures.
