An interview is essentially a structured conversation where one participant asks questions, and the other provides answers. In common parlance, the word interview refers to a one-on-one conversation between an interviewer and an interviewee. The interviewer asks questions to which the interviewee responds, usually so information is offered by the interviewee to interviewer -- and that information may be used or provided to other audiences, whether in real time or later. This feature is common to many types of interviews -- a job interview or interview with a witness to an event may have no other audience present at the time, but the answers will be later provided to others in the employment or investigative process. An interview may also transfer information or answers in both directions. Interviews usually take place face-to-face and in person. In some, the parties are separated geographically, connecting by methods such as videoconferencing or telephone interviews. Interviews almost always involve spoken conversation between two or more parties. In some instances a conversation can happen between two persons who type their questions and answers. Interviews can be unstructured, free-wheeling and open-ended conversations without predetermined plan or prearranged questions, or highly structured conversations in which specific questions occur in a specified order. They can follow diverse formats; for example, in a ladder interview, a respondent's answers typically guide subsequent interviews, with the object being to explore a respondent's subconscious motives. Typically the interviewer has some way of recording the information that is gleaned from the interviewee, often by keeping notes with a pencil and paper, or with a video or audio recorder. Interviews usually have a limited duration, with a beginning and an ending. The traditional two-person interview format, sometimes called a one-on-one interview, permits direct questions and followups, which enables an interviewer to better gauge the accuracy and relevance of responses. It is a flexible arrangement in the sense that subsequent questions can be tailored to clarify earlier answers. Further, it eliminates possible distortion due to other parties being present. Face to face interviewing helps both parties to interact and form a connection, and understand the other. Further, face to face interview sessions can be more enjoyable.
