ALTEN interview questions

I have been contacted via Linkedin in March 2017. After a phone call, I went forward to the face-to-face interview in Alten Sophia Antipolis. Terrible experience! First of all they asked me if I preferred French or English; I told it was pretty much the same, hence we continued in English. At the end of the interview, suprise! The HR told me that I coul not match any of their position because I did not speak French. But this was her deduction from the fact that, between French and English, I choose English for the interview. Second: after having asked me about my profile and expectations, the HR told me that my profile has nothing to do with what they were looking for. Ok, I understand; the problem is that they had contacted me and organised the interview. Finally, I had the impression they organize interviews just to collect data about people on the market and/or to show they are working. Honestly, I do not expect Atran to care about my time, but I have never met a company with so small consideration of its own time. HR not serious, and if HR is the mirror of the company.....
