Domande di colloquio presso ART Computer

They said in the interview that they would first of all check my french level with a native colleague of their company so It would not be a waste of time for me. I talk to a french woman and she said my french is fluent, good with rich vocabulary. But the recruiter said the Swiss Client is a nationalsocialist with another more strong word with these words and that once she hired one Arab person and she had to fire her as they did not appreciate their accent. I will skip the judgement, but I suggest the Hr department ensure a positive vocabulary during the interview. Now I have received an email saying another candidate match better with the offer. My second question to them, is Why they just don´t hire someone from Switzerland? Thanks
