During my education there was much literature about M&A, IPOs and stuff like that. At the moment I am only familiar with the theory, and just want to check out how it is in practice. And it would be even better if I could experience this in Switserland.
I saw CS also has an internship possibilities for M&A for the swiss market, which is also fine by me. They don't have to be international imo.
UBS on the other hand offers an internship in their IB department which is more international. However, I don't have a lot of experience at the moment. So, other departments also sound very interesting to me. The best case for me is actually to work in several departments to find out what I really like and be good at and afterwards apply for a full-time job
