Just after graduation, I applied online with a resume and cover letter. I was contacted by a recruiter within 3 weeks to set up an over the phone interview. This first interview with the recruiter was just a screening process, asking very generic questions. Second interview was again over the phone with the Lead Engineer in the department. He asked a few technical questions, asked about classes I had taken, and went in depth through my resume. After about 2 weeks I was called to set up an on site interview in Boise. Micron paid to fly my out, for the hotel, and rental car, and gave me the option to bring along any significant others that would be making the move as well. The on site interview was 4 hours long, with 3 interview sessions. The first was with the same lead engineer I spoke with on the phone, the second was with two of his peers, and the third was with the department head. All three were very similar. The were a combination of seeing if I was a good cultural fit as well as digging into my technical fit for the role. The questions involved explaining my thought process as well as using a whiteboard for example. After the interview it took about 4 weeks (and a little badgering on my part) to get the final word.

Online interview with several people followed by face to face interview with a hiring manager at the location. Lasted around 40 minutes each. Quite a long waiting process, around 2 weeks from each.
