Had a final interview entirely in French for a job that only required fluency English without no prior warning or explanation or even being asked if I was okay with it. French language was not mentioned in the job advert and it was clear the interviewer chose this language because she was more confortable with it than English HRBP was not very welcoming, it felt more like an interrogation than a pleasant conversation so I never felt at ease . I decided to dropout of the process because of this poor experience.
