Intel Corporation Hardware Engineer interview questions

1 phone screen followed by onsite interview since I was local in Austin. I had total 3 interviews onsite. The person who phone interviewed me was nice and the manager was nice too but the 3rd person was so rude it was like he did not know the basic etiquette of professional meeting environment. So here's what happened: this was last of all interviews and maybe they had already decided that they did not want me or something. This guy comes in the conference room and starts asking me tough questions, fair enough. Next thing I know, he takes out his cell phone in middle of me giving an answer and starts looking at it and the "new tv" that they seemingly put in that conference room. He kept interrupting me and saying that he was trying to match the time on his phone and the tv screen and thought the time on tv screen was wrong. At that time I was desperate for a job and did not say anything to the manager about this behavior. But now that I think about it, I would not work in such a team.
