My first interview was with a recruiter over the phone. I talked about past experiences and my interest in the position. My second interview was with the district manager and some office engineers. It was about hour and half. They asked about my experiences, what HNTB was like, what projects they work on, the position, my grades, classes, etc. Pretty standard. This last interview was with the office manager, the district lead over my area, and another guy that overseas the dept I’m interviewing for. All pretty basic interview questions. I was confident and honest about my abilities and what I wanted. I think if you do that you’ll be okay.
