High enthusiasm about long lasting mentoring relationships and older mentors.

It can be concluded that the expectations of mentors and protégés differed regarding the content and aim of the interpersonal characteristics of their mentoring relationship. We recommend mentors and protégés to more explicitly exchange their expectations of the informal mentoring relationship, as typically practiced in formal mentoring. Additionally, in our study, seniority and lasting relationships seem crucial for good informal mentoring. It appears beneficial to foster lasting informal mentoring relationships and to give more guidance to younger mentors.
