My resume was pulled from Intel's database and I was initially screened via phone by my to-be manager. First interview was very simple; covered demographic information, some of my MS research and projects, and one or two questions about how the tools we use work (materials characterization position).
Had a second phone interview a week later with another group member who will most likely be training me. This covered some of my work again, but focused more on what the position will be like and our group's role in the overall process. This almost seemed like an informative phone call.
About a week later I was contacted to schedule an on-site interview, which happened the next week (2 weeks after the second phone interview). The folks at Intel were aware that I was taking time out of my vacation to interview, so they booked me a quick trip (in Sunday, out Monday evening). Everything was completely covered, and I think I actually made money with the per diem.
The interviews were 6 30 minute meetings with the individual group members, including my several managers, our group leader, and one of the newer guys. No really difficult technical questions; mostly just asking about my research and some basic imaging questions. Ate lunch with them afterwards and then got a quick tour of the facility before heading to the airport.
Received my offer within a week of the on-site interview (my hiring manager was very prompt, which is definitely not the norm).
