Interviews have been used for decades in empirical inquiry across the social sciences as one or the primary means of generating data. In applied linguistics, interview research has increased dramatically in recent years, particularly in qualitative studies that aim to investigate participants’ identities, experiences, beliefs, and orientations toward a range of phenomena. However, despite the proliferation of interview research in qualitative applied linguistics, it has become equally apparent that there is a profound inconsistency in how the interview has been and continues to be theorized in the field. This article critically reviews a selection of applied linguistics research from the past 5 years that uses interviews in case study, ethnographic, narrative, (auto)biographical, and related qualitative frameworks, focusing in particular on the ideologies of language, communication, and the interview, or the communicable cartographies of interviewing, that are evident in them. By contrasting what is referred to as an interview as research instrument perspective with a research interview as social practice orientation, the article argues for greater reflexivity about the interview methods that qualitative applied linguists use in their studies, the status ascribed to interview data, and how those data are analyzed and represented.
