Unstructured interviews are a type of qualitative research method where the interviewer asks open-ended questions without a fixed format. This allows for a natural flow of conversation, enabling participants to express their thoughts and feelings freely. The flexibility of unstructured interviews can lead to rich, detailed responses that provide deeper insights into the subject matter. These interviews are often used in fields like psychology, sociology, and market research to gather in-depth information. Since there is no strict guideline, the interviewer can adapt questions based on the participant's responses, making it easier to explore complex topics and uncover new ideas.
