Most interviews follow a basic format.
Most interviews, however, will range from open-ended, in which the interviewer asks questions and lets you do most of the talking, to the highly structured, in which the interviewer asks many specific questions following a planned format. The interviewer will establish rapport and create a relaxed, though businesslike, atmosphere. This is where the interviewer gets the very important first impression of you. Focus on what you are like, and what you have accomplished, your academic and work background, and your goals. One of the interviewers objectives is to see if your qualifications match your declared work interests.
