Intel Corporation interview questions

Starts very early in the morning around 8am with several interviewee waiting at lobby (about 9~10 of us). The upper level manager came welcome us with a short intro then took us to get temp badges. Afterwards, he tool all of us to a row of conference rooms to do a round robin style interview. Each room had two direct manager (usually with different field) and took about 1hr for each room. I believe each one of us went through 4 rooms. The questions are generally about behavior but sometimes simple engineering concepts. The upper level manger came and took us for lunch and also guided us a window tour at end of the day.
