The document discusses different types of interviews and procedures for conducting interviews. It defines an interview as a meeting between two people to exchange information and ideas through questions and responses. There are several types of interviews, including structured interviews which have explicit research goals similar to a survey, and unstructured interviews which have an implicit research agenda and allow questions to emerge from the conversation. When conducting interviews, it is important to establish trust and make the interviewee feel comfortable, while also using an interview schedule or guide to cover relevant topics. The goals are to understand the interviewee's perspective and interpret their responses in the proper context.
