Phone Interview: Got email to schedule phone interview. In phone interview (2 interviewers), asked to walk through resume, and asked technical questions about things on resume (know everything on your resume very well). Asked behavioral questions like how to deal with conflict, when you showed leadership, etc. Guys on interview were very friendly, and also helpful later throughout the interview process.
Scheduled for on-site interview 2 weeks later, but had to push back since HR didn't process fast enough.
On-site interview consisted of five 30 min 1:1 interviews, one hour presentation on my dissertation research, and lunch. I was escorted by an engineer on the team throughout the day, and had lunch with him in the cafeteria. The 1:1 interviews were with managers and team leads. Presentation was in front of a bunch of engineers.
1:1 interviews involved mostly behavioral questions like how to deal with conflict, how to deal with ambiguity, when did I solve a problem, what do I do outside of work, examples of collaborating with people of different backgrounds. Also questions involved things on resume and technical questions about my graduate studies. Only technical question was about what is most important mechanical property of substrates (answer: coefficient of thermal expansion), followed by questions about how to alter the CTE.
The dissertation presentation was not too difficult. Important things to note: Make sure you can fit it into an hour with questions (probably 30 minutes rehearsed), make it accessible to people who do not necessarily have the same background. People will be walking in and out of your presentation.
Intel pays for airfare, 2 nights in decent hotel, 3 days rental car. They give a flat rate Visa check card to cover incidentals. All of the engineers were very nice, however managers don't tend to reply to email follow ups, but the original phone interviewers are quite responsive. I was told I would get a decision in a week, but it came in 2, not too bad.
