Intel Corporation Software Developer interview questions

I got referred by an acquaintance to the Windows OS team at Folsom. The overall interview process was around 3-4 weeks. I had an initial round of phone interview which concentrated on general operating system concepts. I was invited for an onsite interview at Folsom, CA. It was the worst experience that I have had in an interview. I think that the decision regarding hiring was made well before actually even interviewing me. There were 7 rounds of technical interviews. First round was good with generic discussion about my projects, operating system concepts etc. Second round was by an engineer with no proper communication skills, he was rude, unwilling to hear to my approach to problems. This was supossed to be a x86 coding round when I had no where listed that on my resume. Most of the rounds were primarily concentrated on computer architecture when I had very limited knowledge on the same. The interviewers seems very inconsiderate of the fact that I was a computer science student and not a CE student. The lunch interview was a pain, right from the moment we left the meeting room, till we came back the interviewer was constantly asking questions, with very limited time given to even have my food. I was expected to code on paper even the lunch interview round which seemed pretty insane to me. The worst part was the same team at Hillborough had no CE questions at all that were asked while interviewing the candiates.
