NoUser wrotebtw i have applied to this company randomly, i got accepted, and i don't even speak french :P
I am applying a master (CS) in France but to be able to apply you should pass a french test and later an interview.
can't help with the unis cause didn't check the ones in Paris, but Paris VI (Pierre and Marie Curie University) in the best in France, you can check it out.
you can visit this site :
http://www.liban.campusfrance.org/
and you can go to the "Campus" next to the embassy and ask for more info, cause if you are not French i don't know how you can apply from France, cause as far as I know the validation and interview are done in the "Campus" located in al mathaf ; I'm not sure if they will redirect you to an office in Paris or something similar. Better go there and ask the questions you need to ask.
