Intel Corporation Device Engineer interview questions

I applied to the job through the Intel website and was contacted about two weeks later to set up a phone interview. I was then invited for an on-site interview in Oregon a few days later. The interview consisted of a one-hour technical presentation first thing in the morning, followed by 6 or 7 one on one interviews with managers and engineers in the group, lasting 30-60 minutes each. About a month after my interview I was notified that I would not receive an offer.
