When you are going on an interview, it is important that you have a list of references ready. Ideally, an accurate reference sheet will consist of previous supervisors from your three most recent jobs. It will include the full name of each supervisor, title, company, current phone number and email address. It is helpful to get permission from each reference prior to your interview to ensure that he or she is available and willing to be a reference for you. A prepared list of references will show your potential employer that you are organized and responsible.
