An interview is a conversation where questions are asked and answers are given. In common parlance, the word "interview" refers to a one-on-one conversation with one person acting in the role of the interviewer and the other in the role of the interviewee.
Brief and to the point. Not difficult at all. Would recommend giving it a try. Always have a positive mind and offer feedback. Even when the interviewer themselves seem to have a bad day, be your best.
