Tóm tắt	A pilot-tested semi-structured interview combines the flexibility of semi-structured interviewing — a guide of open-ended questions allowing conversational depth — with a mandatory pre-study pilot phase in which the guide is trialled on a small subset of participants or informants. The pilot reveals ambiguous questions, poor sequencing, and missing topics before the main data collection begins, substantially strengthening the validity and efficiency of the final instrument.	An online semi-structured interview is a qualitative data collection technique in which a researcher conducts a guided but flexible conversation with a participant over a digital medium — video call, telephone, chat, or email — using a prepared interview guide with open-ended questions while remaining free to probe, reorder, or add follow-up questions as the dialogue unfolds. It combines the accessibility of remote communication with the depth and adaptability of semi-structured inquiry.
