I interviewed with HR on my college campus during the Fall Career Fair (October 2nd). I then received an email from HR at the end of October informing me they were still reviewing candidates and positions. I contacted HR by phone a couple of times in the next couple of months. I was very patient because it was the Holiday season and I knew that it was a busy time for everybody. Some time after New Years Day, I was able to secure an interview at Emerson in Chanhassen, MN.
The interview process was rigorous, but helpful. I arrived and was offered lunch with my college's alumni. I was then interviewed by 3 times, each by 2 engineers. In general, it was a manager from a specific department and a veteran from the same department. There was also a tour and an HR interview. Paperwork was filled out on site, so be prepared to have your work history and at least 2 contacts and their phone numbers for the background check.
