This is the type of question an interviewer at Amazon will use to begin the conversation, learn more about your background, and collect information they can use throughout the interview. This question also provides you the opportunity to direct the interview towards a subject area that you are familiar with and comfortable responding to questions about. Throughout the interview, keep your answers brief and to the point. This will encourage the interviewer to ask follow-up questions about the same topic or move on to a new subject.
