This article explores pre-service English teachers’ self-reflections as participants in online intercultural exchange (VE). The aim is twofold: to examine participants’ perceptions of intercultural experiences in response to VE; and, to understand whether and how teacher trainees gain pedagogical insights through self-reflection situated in a cross-cultural online project. The study draws upon two iterations of exploratory research in a VE-project carried out with two cohorts of student groups. The first cycle involved students in Indonesia and Sweden, and the second cycle, a three-way collaboration, involved students in Argentina, Poland and Sweden. This article focuses on the Swedish side and examines empirical data incorporating e-diaries and interviews. A qualitative transcript analysis generated three intersecting themes: language and power, politeness, and participation through digital tools. Two theoretical constructs provide the analytical lens: persona (Hinrichsen & Coombs, 2014) and liquid interculturality (Dervin & Dirba, 2006). The findings challenge fixed notions of identity and interculturality, showing how participants engage in negotiations and fluid constructions of persona in response to perceived expectations of their interlocutors. The findings also indicate affordances of VE as a lingua franca contact zone in developing pre-service English teachers’ self-awareness and pedagogical competences.
