สรุป	A face-to-face semi-structured interview is a qualitative data collection technique in which a researcher meets a participant in person and follows a prepared topic guide of open-ended questions while retaining the flexibility to probe, reorder, and explore emerging themes. It combines the consistency of a predetermined agenda with the depth and responsiveness of an open dialogue, making it one of the most widely used methods in qualitative and mixed-methods research across the social, health, and educational sciences.	The in-depth interview is a one-to-one qualitative data-collection method in which a researcher engages a participant in an extended, open-ended conversation to elicit rich, detailed accounts of experiences, perceptions, beliefs, or meanings. Unlike structured surveys, the interview guide serves as a flexible road map rather than a fixed script, allowing the researcher to probe unexpected directions as they emerge. The approach is foundational to qualitative inquiry and is used directly as a primary method or as the data-collection arm of phenomenology, grounded theory, narrative analysis, and other frameworks.
