Intel Corporation Process Engineer interview questions

I applied through employee referral. Had a phone interview, then onsite (in Hillsboro, OR) interview after 20 days and finally a job offer after 7 days of onsite. Whole process took about a month and was very smooth. A 9am -3pm interview : 45 min presentation ( 5 audience) in the morning, followed by 3 one-one interview with group leader, plant manager and lab manager (latter 3 were not part of the presentation).

I first had an informal interview with a recruiter on campus who forwarded my resume to a different area manager. The next day I was invited to go to the Intel Campus in Hillsboro, OR for an interview in two weeks. The interview day began at 8:30. I first did a presentation on my thesis work for 5 people, then a one on one technical interview about my research and different things I listed on my resume. After that was a behavioral interview where the interviewer asked about conflict and teamwork. After that was lunch and fab window tour. Then a quick meeting with the area manager who will ask more questions similar to ones asked earlier in the day. The AM that I met didn't seem to be that interested in me which I guess explains why I didn't get an offer. They also don't give any feedback on what went wrong, so I'll never know.
