I got a phone call after 8 months from an online application. I had a 45 minutes phone interview, technical and behavioral. Asked me to explain my research, how much time you have to spend to do any experiment, how some characterization techniques work. After three days, got an email saying they would like to have me on-site.
On-site interview started at 8:45am with 1 hr technical interview with the group leader. Mostly I was explaining my research to him in a very simple manner, and tried to give broad application picture. He asked me how NMR works, what are conditions you change to make your expt work, how many people you worked with, so on and so forth.
I had five 1:1(actually 2:1) interviews mainly consisting of questions like - what was the biggest challenge you solved?, did you ever had a conflict with your adviser or coworker?, how you train or guide people? Why not to work for any other Chemical company, why Intel? Weakness and strength? Can you work overtime?
I had 1 hour talk which mainly consisted of people from my background (I think that's how Intel organizes the interview). Try to make a very simple and high impact talk, don't overload with data. Try to answer all the questions to the fullest.
During lunch time, they gave us presentation on what they do and what we need to do.
Last interview was with the area manager(at 4pm). It was mainly wrap up, no big questions, very short.
Overall, Intel makes the interview process very friendly and relaxed(as most of the interviews were in cafeteria).
I heard back from them after 45 days of my on-site interview, they offered me a job. Really good compensation!
