I applied through college or university. The process took 1+ week. I interviewed at Cummins (Madison, WI) in Feb 2015
Interview
Mostly behavioral, asked about the experiences in the resume. They try to see if you are a good problem solver and if you like to work in a team. Be prepared to answer detailed questions about your resume and also what you got out of those experiences in a big picture.
Interview questions [1]
Question 1
They asked about one tiny detail on my research project I did 3 years ago, and I got stumped.
