If the mentor thinks they may be a suitable mentor for you, they will contact you directly using the email address you supplied. They will arrange to have an exploratory meeting with you for both of you to assess whether the mentoring relationship might work (see our guide to the exploratory meeting).
This may be face-to-face, or via Skype/Facetime or equivalent. If on reading your request the mentor thinks they aren’t suitable for you, you will receive a standard reply through the Mentor Connect website. Please don’t take this as personal rejection. And please do search again and submit another request.
