I first became interested in Rockwell at an event they held on my campus where I gave them my resume. A couple weeks later I received an email about setting up a phone interview. This was a pretty basic interview - just discussed my resume and their products/what they do at Rockwell. I then was contacted for an on-site interview which lasted about 3 hours. This consisted of two technical interviews, a tour, and lunch at their facility. The interviews weren't too difficult and mostly covered some basic data structures and other questions about object oriented programming.
