Cummins Applications Engineer interview questions

I submitted my resume through career center web page of my college and got invited for the on-campus interview. I was interviewed by two representatives. One was a sr. engineer and the other person was alumni from my college. The sr. engineer was typing my answer while the other man was asking me question. Both of them were pretty nice.

First, I had a phone interview with a Recruiter. She asked me basic behavioral and background questions. She was very nice and not at all intimidating. I was then asked to do another phone interview with two engineers. They asked me more background questions and specifically wanted to know about my customer experience background. I had never been asked about that in any interview in the past. About 10 days after that interview, I received an offer letter.
