Read the passage carefully and give the answer of following questions.

The interview may be conducted by letter and by telephone, as well as in person. Letter and telephone interviews are less satisfactory. Direct contact with an individual and a face-to-face relationship often provide a stimulating situation for both interviewer and interviewee. Personal reaction and interaction aid not only in rapport but also in obtaining nuances and additional information by the reactions which are more fully observed in a face-to-face relationship.

Adequate preparation for the interview is a “must”. Careful planning saves not only time but also energy of both parties concerned. The interview is used to obtain facts or subjective data such as individual opinions, attitudes, and preferences. Interviews are used to check on questionnaires which may have been used to obtain data, or when a problem being investigated is complex, or when the information needed to solve it cannot be secured easily in any other way. People will often give information orally but will not put it in writing.
