I have been in my "career" for 2 years post-uni and have recently been offered the place of getting a mentor (my work formally interacts with a regional business network/charity thing which does mentor matching as part of its remit, especially for minority groups). This is intended to be a long term thing (2 - 5 years was the guideline my contact suggested is normal) so is not conditional on me being employed where I am at the moment, though.
I've excitedly accepted, and I have my first coffee chat with my mentor planned for the end of next week.
After I introduced myself via email, my mentor suggested I have a think about where I am, where I want to go, what kinds of things they can help me with, and although I know from a high level point of view where I want to be in, say, 5 years, I'm not sure about how to present some of the other things that are scheduled for discussion. How much detail to go into, that sort of thing.
Bearing in mind that my mentor has over 25 years in the field, and is currently employed in a formal/official capacity as a mentor (they are a spokesperson for another, very similar charity organisation which operates in my sector)... I just want to ensure that I get as much value out of this opportunity as I can. For the record, I'm a minority in the sector I work in, which is typically white, middle aged, male and a haven for business golfers 
So if anyone can offer me any advice as a mentee, such as pitfalls to avoid (I can imagine the obvious ones - don't waste my mentor's time, be careful about setting boundaries so that I don't become overly familiar, stick to agreed schedules/action lists - naturally!)... I'd be very grateful!
I'd be interested to hear from both sides what makes a good mentor/mentee relationship? There must be lots of MNers who've been involved in this type of thing...
