Mentoring is about passing on valuable skills, knowledge and insight to a mentee with the purpose of helping them develop their abilities. While coaching is used in a variety of fields, mentoring is usually employed in organisations as a way of efficiently transferring valuable competencies from one person to another. Therefore the mentor and mentee tend to have different seniority levels.
