I had 2 interviews, the first interview was with 2 engineers from 2 different plants of Cummins (Columbus, Jamestown), second interview was with 1 engineer (Columbus) First interview, it's behavioral, they ask you questions like: Describe a moment when you were challenged by a project? and some diversity question like: Describe a moment when you had to work with someone from another culture? Second interview was pretty much behavioral too, but with some easy technical questions, I remember I was describing a project I worked on and first try it failed and so my interviewer asked me: how did you fix it, and why did you think that was the issue? Pretty straight forward and easy.
