The knowledge, advice, and resources a mentor shares depend on the format and goals of a specific mentoring relationship. A mentor may share with a mentee (or protege) information about his or her own career path, as well as provide guidance, motivation, emotional support, and role modeling. A mentor may help with exploring careers, setting goals, developing contacts, and identifying resources. The mentor role may change as the needs of the mentee change. Some mentoring relationships are part of structured programs that have specific expectations and guidelines: others are more informal.
