An interview is a conversation between two or more people where the interviewer asks questions to obtain information from the interviewee. There are two main types of interviews: assessments which evaluate a person, and informational interviews to gather facts. Television interviews can be either extended, using multiple cameras over a longer period, or short segments typical for news using one camera and minimizing equipment needs. Proper interview techniques include pausing between questions, using cutaways to cover edits, and focusing first on a tightly edited audio version before addressing video transitions.
