They are just asking about our passions dreams etc. It wasn't very difficult I can say. Try to talk too much and make yourself look extremely social and friendly person. I personally haven't really went so hard on it, my purpose to apply for it was that I wanted to get the experience, so just tried to be honest and they already liked it. They really care about your energy in life.

First- Skype call (very easy) Second- Another Skype Call with Managers (just need to be a dreamer) Then hiring process which doesn't really take long because Aiesec visa is valid in most of countries of the world.
