Many companies use the terms interchangeably, but coaching is not mentoring. The coach is oriented to change as opposed to a mentor, who is oriented towards growth. In coaching, the relationship with the client generally has a set duration. A mentoring relationship can last for a long time.
Coaching is generally more structured and meetings are scheduled regularly. Mentoring meetings can be more informal and might happen only when the mentee needs or wants advice. Coaching is more short-term and focused on specific issues or development needs, whereas mentoring takes a longer-term view and a broader view of the mentee’s career and personal development.
