The interviewer has no predetermined set of specific questions. The respondent is encouraged to talk about particular areas that are of interest to the interviewer. These may be very general, or even quite vague at the outset. The interviewer lets the respondent talk and responds to what is said to keep the interview going.
The aim of this kind of interviewing is to allow respondents to talk about what they see as important. The interviewer then has to guide the conversation onto the areas of interest to the research or probe the taken-for-granteds of the respondent to try and get a better understanding of the way the respondent makes sense of their world (see, for example, CASE STUDY: Distorting the truth).
