Transportation Research Center interview questions

I got a call from a TRC recruiter who briefly discussed the aspects of my job and a little bit about my background (He saw my resume posted online). That went fine, so he then sent my resume to his superiors to check their interest level. Scheduled a phone interview with multiple people (2 or 3 total) on the line that lasted about 15-20 minutes. Several weeks later, I got invited to answer a few more questions and fill out paperwork where I was offered the job.
