Unstructured interviews are a type of qualitative research method where the interviewer asks open-ended questions without a fixed format. This approach allows for a natural flow of conversation, enabling participants to express their thoughts and feelings in their own words. It is often used in fields like psychology, sociology, and market research to gather in-depth insights. In unstructured interviews, the interviewer may explore various topics based on the participant's responses, leading to a more flexible and dynamic interaction. This method can uncover rich, detailed information that structured interviews might miss, making it valuable for understanding complex issues or experiences.
