At some point in the interview process, if a potential employer is seriously interested in you, they're likely to ask for references. Have them prepared in advance, on a separate sheet of paper. Typically, four or five references should be plenty. List the person's name, their title, company name, and business telephone, with their direct line, if possible. Some people also include the number of years known. Use nice quality paper, and be sure to leave space between each entry. References are especially important if you've been fired. Assuming you've maintained a civil relationship with your former boss, he or she will probably give you a good reference. Your boss may even agree to write a reference letter for you, or sign a letter that you've drafted. Ask them which method they prefer. It's best to leave references off your resume, though you may mention them as available upon request.
