The process took 1 day. I interviewed at International (Lisle, IL) in Nov 2011
Interview
Had 1 hr long panel interview that consisted of all behavioral type questions. It was a very strict and direct interview, there wrote down all my answers.
I feel like I could have done a better job on answering the questions asked.
Note for future candidates, practice and ace the STAR interview technique. It is essential for Navistar Interviews.
