B4 or Wealth Management?

Hi, please to meet you all, this is my first post here...

I am from Milan (Italy), I'm 24 and I'm about to finish my degree in Business Administration. I'm not from a target school and I need a career advice from veterans.

My plan is to finish my degree (yes I'm late) and do 1/2 internship before do my MSc in Finance at RSM (target in Benelux). For the internship I was thinking about credit suisse or deutsche bank since they are here in my area, but also to a big four since all four here are present. My long term goal is to break in IB, I don't know what internship is better for my goal and maybe if I choose the correct MSc ( I like because the ROI since I pay less because I'm EA citizen), thank you all
