It is not that simple I'm afraid. French students themselves struggle to get into Air France (they haven't hired openly in a while, lots of internal movement from HOP, transavia etc).
Before even talking about language difficulties with Air France though or indeed any other airline, the reality is you will not be hired anywhere by a European airline whilst you don't have the right to live/work here, and as I'm sure you're aware ... there is absolutely no shortage of CPL/IR qualified pilots here whatsoever unfortunately. It really will not happen.
You will have to look at home or maybe try Asia etc
