This may be unusual - not everyone's experience may be like this.
During general introductions, the recruiter criticized my former employers and used some adjectives to compare them with NVidia. In trying to establish that they don't negotiate salaries, commented on my past choices.
I gave factual, courteous answers and focused on actual interviews that were about to start.
Sometimes recruiters don't realize that polite candidates might let unwelcoming language pass without retort, but they are impacting the NVidia's brand as an employer.
The interviews were fine in general but we didn't seem to be a match. I don't get surprised by odd questions or behaviour, but interviewers tended to cut my answers off mid-sentence. They did not like me setting context for my answers to what seemed like theoretical situation MCQ list. The role requires soft skills and situations are not black or white.
