Intel Corporation interview questions

Contacted for phone interview which lasted about 30 minutes asking various questions about research and fundamentals of instrumentation I use. Conversation ended in request for onsite interview the following week which started at 8am with a 45 minute interview followed by a one hour presentation on my work, followed by 45 minute technical interviews until about 5:45 and another 45 minutes with the hiring manager. Most engineers were young, working at Intel for anywhere from 6 months to 5 years, but mostly in the 2-3 year range. Certainly the "fresher" the employee the more enthusiastic they were.Questions were generally technical with lots of "do you have any questions?" I think they largely are trying to gauge your interest in the position, considering it's a big jump from research to process engineering/optimization. The more senior employees lacked much of the enthusiasm and tended to ask more practical questions, see below.
