Clark Construction Group Office Engineer interview questions

After submitting my resume I was contacted by the HR department who set up a day of interviewing. They put me up in a hotel across the street which was nice considering I was only coming from 2.5 hours away. In the morning there was a brief overview at headquarters and then I was taken to a job site for the day by metro. I was shown around the job site(seriously, a suit isn't necessary and you'll be better off without nice shoes) by a current office engineer for the remainder of the morning which was interesting. I ate lunch with a few of the younger people on site and after lunch I interviewed with the project manager on site. The people were very nice, but it seemed like a very mediocre kind of place.
