A growing number of studies have examined qualitative research interviews in terms of how researchers' own identities and agendas are implicated in the construction of interviewees' responses. Adopting the constructionist conception of research interviews, the current study introduces a comparative analysis of 2 interviews with a multilingual speaker of Korean, English, and Japanese conducted by 2 researchers who come from distinctive cultural, linguistic, and professional backgrounds. Informed by ethnomethodology, conversation analysis, and membership categorization analysis, the current analysis reveals how the interviewee came to co-construct a different set of accounts with each interviewer in comparable segments where the same topics were discussed. The focal segments examined in this study can be seen as an illustration of how this Korean student interacting in her everyday life with others may co-construct her ever-shifting identities vis-a-vis membership categories such as American, Korean, or Korean-American.
