Intel Corporation Senior Process Engineer interview questions

I cam to know about the position of Senior process Engineer at Intel Corporation via University Recruiting. I send my resume and cover letter to the recruiter and I got an email for telephonic interview after three weeks from the hiring manager. Telephonic interview was about company's job description and my Ph.D. research work. I was successful ib convincing the hiring manager and I got the offer for the site interview. I was told that it will the day long interview with one hour presentation of my research work. On site interview started at 9;30 AM in the morning with interviewers changing every 30 minutes. These were behavioural as well as technical questions. During lunch time, we grabbed food from cafetaria and we attended company's seminar. We were also given fab's window tour after my research presentation to the prospective hiring group. The final interview was taken by the Area Manager and we left at 4:30 PM. After two weeks, I got the offer letter. However, due to my Ph.D. graduation and work authorization issues. I joined after 5 months of receiving the letter.

Gave resume to a recruiter at a university job fair. A couple of weeks later got a phone call asking basic questions about availability and interest in the position. They flew me out and paid for accommodations and food for 3 day trip. Interview started at ~9am and a couple of 1 on 1 personal interviews with managers. They discussed the position, requirements, and company ideals/motto/goal/functionings. Next came a 1 hr presentation on my university work which was attended by a small group which then took me out to lunch were I could ask questions about what the day to day job was like. This was followed by more one on one interviews with higher managers discussing any clarifications to questions that had arise through the process. Following the interview, I was allowed to explore the city with my extra time to get a feel for the area. Within a few days, I received an email stating that they wouldn't make me an offer for the position.
