Hey again
Firstly, overseas exchange can be a 6 week winter/summer program, a semester exchange ranging from 5-6 months, or a full years exchange where you can attend one university for a semester then fly half way across the world if you wished and attend another university, it's entirely up to you
The benefits of exchange are brilliant, in fact there are no negatives in my opinion, everyone should try and do it! You are able to learn different ideas from different universities around the world, the whole experience of studying at another university should make you such a more well rounded person. Yes, you do get to experience different cultures, and you will gain immense amounts of independence, but exchange really will make a difference in the long run. You should gain so much more confidence and self belief in doing things, this potentially flowing through to your career. Most university graduates don't have much to differentiate themselves from one another (if someone says prestige, i'll lose it) so going on exchange demonstrates to employees that you are someone who must hold self-belief and initiative. And yes, you would be able to put the university which you attended on your resume, but I do suggest undertaking at least a semester abroad, you'll thank yourself for it believe me!
I've currently applied for exchange to Berlin School of Economics, just waiting to hear back from MQ intl to see if i've been accepted!
