The most important and useful thing you can do to prepare for an interview is practice. Study the common interview questions listed below and practice answering them. It may even be useful to write out the answers and read them several times – including right before the interview. Practice in mock-interview situations. Practice with your friends and family.
Analyze your answers and determine what will set you apart from other candidates. Relate those qualities and characteristics to the kinds of questions that will be asked in the interview. You can also use mistakes made in the past as examples of self-improvement if you have taken the initiative to improve in those areas.
