Asking questions is an important opportunity for you to learn more about the employer, and for the interviewer to further evaluate you as a job candidate. It requires some advance preparation on your part. You should prepare at least five good questions, though you often won't get to ask that many. Ask questions concerning the job, the company, and the industry or profession. Your questions should indicate your interest in these subjects and that you have read and thought about them. For example, you might start, "I read in NBR that ...Do you think that is going to have a major impact on your business."
