Hi,If you're interested in voluntary work, I can recommend AIESEC (www.aiesec.org) as an excellent organisation to develop a variety of skills - e.g. leadership, teamwork, entrepreneurship, cultural awareness, international travel etc.If AIESEC has offices at your university, I would certainly encourage you to think about it.I was a member when I was a student, and I felt that it really helped me to break into strategy consulting. But more importantly (and this has already been emphasised by previous posts) , it was something that I really enjoyed.Good luck with choosing the right ECs for you, whatever it is, just make sure you do it because it interests you rather than just for your CV.
