Got my interview today in Paris and I was successful!!
It went really fast, 1h30min
I'm not gonna detail the steps by steps but the CO asked me about what kind of job I was doing in France, my educational level, how much do I make, How much did I save for my travel to the US. They also asked if I was going there alone, no children etc...
They made me raise the right hand and swear I was saying the truth (I never heard people who got this).
So it went well, they were very nice and professional. One CO even made jokes.
I only spoke English in the last part of the interview.
And that was it

what a relief! I wish good luck to all of you.
