Intel Corporation Systems Validation Engineer interview questions

The initial communication was a phone call from an HR rep to set up a phone screen. The phone screen was set up for the next day and it lasted about 45 minutes. It was mainly the hiring manager selling the job to me. After the phone screen, an on-site interview was set up for the next week. The interview was set up with 7 people for one-on-one interviews which all lasted 30-45 minutes each. There was also a lunch which served as an additional interview. The interview questions were all very technical. Many of the questions were on subjects that were not directly related with the job that was described to me. After the interviews, the hiring manager and HR rep were very hard to get in contact with. I thought I wasn't going to get an offer given the cold shoulder I seemed to be getting. However, 3 weeks later I was given an offer.
