What kind of post-MBA work are you looking to do? St. Gallen excels at placing in the Swiss financial sector.

Honestly, I don't know exactley where I'd like to work after my MBA.
Financial sector doesn't seem the best choice for me. Would be better working in other industries, in a role focused on inovation.
That's the reason why I was thinking about the corporate sector, but I don't know if in Swiss there are these type of companies...
Pharmaceuticals companies seem to be the most innovative in the future...what do you think?

It will reward you greatly to establish a sort of working hypothesis about where you want to be. That might not be only a quesiton of the role, but of the culture and country, perhaps even the light and the landscape. These are basic questions about life goal and values which are worth starting from. There's a huge amount of innovation in the finance sector, so perhaps you have a more specific idea of what innovation means to you?

Either way, with B2 German upon graduation your options will be greatly limited. Can you defer for a year and learn German intensively while assessing other options?

Thanks for your reply!

I cannot defer the MBA unfortunately because I might be too old then...
I would like to work in conuntries where HSG seems strong in placement such as Swiss, Germany, Austria and so on...
I figured out where I want to work, but I still have some problem to figure out what I can do after the MBA..

Why not try to connect with HSG and see what kind of roles that their MBAs generally go into, beyond finance? Finance, and maybe, to a lesser degree, consulting, tends to be the main focus of St. Gallen MBAs.
