A mentor provides career guidance and support to a mentee. There are two main types of mentoring functions - career functions like coaching and exposure, and psychosocial functions like role modeling and counseling. The mentoring relationship progresses through stages from initiation to separation. Both mentors and mentees benefit, with mentees gaining career advancement and mentors helping develop the next generation. Formal mentoring programs aim to match mentors and mentees but research shows informal relationships may be more effective. Effective mentoring requires communication, setting goals, and awareness of relationship dynamics.
