This is what the people want to see, the interview. But first you must make sure that you know whats going to happen before going into the interview. It's not and interrogation its a conversation. Before diving into the actually interview you want to let the subject get comfortable with you and vise versa. If the subject seems edgy throughout the whole interview then you might lose your credibility. So when interviewing someone you always want to ask questions that start with, "Tell me about..." or other sayings of that nature. Another important point is that after each question give the subject time to think and answer. Even if they don't answer right away wait. These points are essential for a well done interview.
