All other Interviewers were great. Unfortunately, the talent acquisition guy was what ruined the dish. His first question in my mail was requiring me to accept offer within 48 hours, otherwise he would move on next candidate. This was not only rude but also was a threat, which shocked me. He then asked for my salary expectation, then insisted a phone call, although I said I prefer email. In the phone call, he brought up the threat of "... otherwise we will move on to next candidate" twice. In the phone call, When pushed for expected salary, I asked him to give a range he said there is no range. Instead he drilled me for a number. The whole process with him is like a battle. I feel much more nervous and uncomfortable when talking to him. No interviewer has made me feel so uncomfortable. He continued to drill to my home address, asked its price, how much sqft, how many bathroom etc, just trying to low ballpark my needed salary in Bay Area. I think he was going too far. Also he asked me how my current company calculated the promotion bonus amount and I said I don't know, he said its "dubious" and he was "confused" since I'm supposed to know the equation based on which the bonus is calculated out. I was really offended because there is nothing wrong that I didn't care my current bonus formula. Overall, he has been aggressive and not based on trust or good faith when talking to me from the very beginning. I have such a great experience talking to all the interviewers as well as other HRs; I had such a bad experience talking to this unprofessional salary negotiator that I started to doubt if I like this company, if this company will treat me like he does, if the company's benefit system will be as aggressive and pushy as he does. If you look at glass door, recruiters is a top dissatisfaction of NVidia and I believe a change on the styles of recruiters like this guy would definitely be a low hang friction to boost NVidias overall score.
