Personal interview means a technique for gathering information through face-to-face contact with individuals. It takes place in a variety of settings-in homes, at shopping malls, in a business office. This type of research is relatively costly, because it requires a staff of interviewers, but it provides the best opportunity to obtain information through probing for clearer explanations.

There are three types of personal interview namely:

i. Face to face: Oral, direct interview conducted by an interviewer. Respondents do not see the questionnaire, but are asked the relevant questions by the interviewer.

ii. In-depth /Expert interview: It is a face-to-face conversation to explore issues; conducted without using a structured questionnaire.

iii. Telephone interview: An interview conducted over the telephone.
