Cummins Entry Level Engineer interview questions

I applied online to their website for an entry level engineer. They emailed me back a few days later to set up a brief 15 min interview, and attached a document that had 5 typical interview questions (i.e. Most difficult and frustrating task I completed, Most innovative idea I've developed, A time where I did not meet a commitment to a peer/colleague, A conflict with a coworker, A confusing project I had to work through). We briefly went over my answers. A couple weeks later I received another technical interview where we discussed my resume and previous projects and skills I have developed. I have been asked for an on-site interview and I will be attending that shortly.
