A structured interview is when all questions are prepared in advance. This is in contrast to an unstructured interview, in which there is no specific set of predetermined questions, and the interviewer is able to change the questions at any time and ask follow-up questions to the interviewee's responses. There are many ways in which you can conduct structured interviews. For example, you can conduct them over the phone, face-to-face, over the Internet, using computer programs, such as Skype, or using videophone.
