On the different mentor profiles, you'll generally see what kind of services a mentor can do for you. Here's what they mean in detail:

1-on-1 calls

The mentor is available for 1-on-1 phone calls. How often these occur is meant to be agreed on between the student and the mentor. They can be irregular and spontaneous or scheduled weekly/biweekly/monthly.

Hands-on-support

The mentor is willing to help the student with job application (CV, Cover Letter, Take-home assignment) review and mock interview. Important: Mentors are not freelancers! Wanting them to do your work is not tolerated.

Career Orientation

The mentor sets weekly goals and activities for the student. These can consist of small challenges and projects or reading material. They are supposed to help towards reaching a bigger end goal.

Chat

The ability for students to chat with their mentor. Every mentor has to provide this service.
