Hello! Newbie here!!

Hello everyone!
I am a new member on this forum, I came here because I face some uncertainties concerning my future career. I am a penultimate year student in Finance in a small French university and I aspire to work in a big Financial firm in the Asset Management field. However, since my school is not well known, I know that I have to do a specialized master in addition to my master's degree in Financial Markets. My question is to know which Specialized master should I follow. Plus what abilities should I acquire or develop to get closer to my dream. Thank you in advance for your input.
P.S: Excuse me for my level of english
