A mentor is defined in the dictionary as "an experienced and trusted advisor" . Advisor is a pretty key word, as a mentor is someone who will guide you through a decision making process offering their own experiences as an aid.
Things from which modules to take, to which jobs to apply for and what to say in an application or interview are all things that my mentor has helped me with so far. Knowing you have someone behind you who is rooting for you gives you the confidence to think you can succeed, and grab every opportunity with both hands to make the time and effort your mentor puts in, worth it.
Usually a mentor has been in the same position as you or at least the same area, and this shared interest makes finding things like work experience a lot easier as they will share industry contacts with you and make the introductions you need to start getting out into the workplace.
Through this experience I haven't gained just my assigned mentor but many others who I had the chance to network with, exchange tweets with and who are there when I need them for advice on which route to take. If you lack confidence in your own ability, are unsure of which direction to follow up after college or university and you are willing to complete and research the things your mentor asks of you the benefits of the scheme are huge...take the opportunity and you will not regret becoming a Student to Stemette mentee.
