DefinitionAn interview (インタビュー) is a survey method in which you talk directly with the people being studied, following up on their answers to draw out facts and views.
ExplanationYou can add or rephrase questions as you watch the other person react, so reasons and background come out. On the other hand, each conversation takes time, which makes it a poor fit for covering many people in a short period. To make good use of limited time, prepare an outline of what you want to ask beforehand.
AnalogyIt is like a doctor taking a patient's history. After hearing when the pain started, the doctor decides on the spot what to ask next.
Memory hookThe word is built from inter (between) and view (see): two people facing and looking at each other.
