Interviews can be structured or unstructured. A structured interview is where the researcher reads out a list of questions and writes down or records the respondent's answers. An unstructured interview is more like a guided conversation, where the talk is informal but the researcher asks questions to ensure that the participant keeps to the subject of the research.
Piloting
A pilot stidy should always be carried out. This acts like a mini test run of the real method. It provides the opportunity to test questionnaires and interview schedules on a small group of people from the research population, in order to check that the questions asked are clear and do not upset or lead the participants and to ensure the method will produce the kind of data that is wanted. The draft questionnaire can be revised if needed to ensure that no problems occur in the real thing.
