Target student is unable to get an interview

Alright so I came here to seek advice and also vent a little to seasoned professionals. 
I’m a French guy, I did prepa and then a top 3 business school. It was difficult for me to even get there because I was really misinformed, didn't even knew what prepa really was at first so I enrolled in a small prepa that had barely ever gotten someone in a top 3 school. I was very proud of that and wanted to use studying at a target to get into IB. 

I have been working to get an internship for one whole year now, and I mean really putting time and efforts into it. I even invested some of my student loan to get into a known French "break into IB" program. I got absolutly nothing, zero, only two round of interviews in a corporate. Those went well but they did not take me. Now I am interning at a small no name auditing firm because I could not get anything else, and of course any bank or boutique I send my resume to see this and reject me. I done all the networking thing, technical training, all. People around me that get in all tell me that they got past the screening because of family or family friends, I do not have that. Also I don't look and act like a typical parisian if that makes sense, of course I dress nice and try to be friendly with bankers I network with, but they very rarely relate to me.

First question is am I already cooked ?
If not, what should I do ? What am I doing wrong ? And if I am cooked what do you think would be a good carrier option for me ? Again I got chasing IB because of prestige and not wanting to waste me getting into a target.
