I was contacted by Intel's HR for an initial phone screen. The initial phone screen was with 2 engineers who were on the team for which I would be interviewing. The questions were technical in nature, but nothing too heavy. I was contacted shortly thereafter requesting that I come out for an on-site interview. Just before I left, I was also contacted by another manager for a second set of interviews while I was going to be on site. The day of my interviews, I went through a series of 1 hour interviews with engineers and managers over the course of a day. Overall, everyone seem prepared and organized for the interview. Some were harder to read than others, but nothing out of the ordinary.
