This chapter explores ethnographic interviews as a method to document the experiences of public service interpreters working in Swedish welfare services. Service encounters are here theoretically defined in the context of postcolonial migration since, similarly to historical colonial encounters, they include administrative procedures, different and sometimes incompatible experiences and worldviews, and they are inherently unequal. Consequently, the in-between position of public service interpreters is ambiguous, as their mandate is to support the equal representation of all participants in an impartial manner. In order to explain the ethnographic interview method, this chapter mainly draws on two such interviews. In the first one, a public service interpreter positions herself as an outside observer and a witness of the encounters in which she performs and highlights what she sees as fatal shortcomings of the institutions concerned. In the second interview, the perspective of the interpreter is that of an insider, a co-participant in an ethically loaded and complex situation. In the conclusion, the author argues that through the interpreter’s experiences, more can be learned about the ambiguity of their position.
