Halliburton Field Engineer interview questions

Got the first interview through our university's career center. They had an info session the night before the interview day where they described all of the different positions available and what it's like to work for Halliburton. First interview was all behavioral questions, nothing too tough. I actually didn't feel that good about it though leaving, so I didn't expect a second interview. About a week later, I received an email saying I had been accepted for a second interview in College Station, TX. They flew me out there a week later, covering all expenses. There were 10 of us there interviewing. The first day we were given a presentation then went on a tour of the facilities. Afterwards, we went out to eat dinner. The next morning we each had one on one interviews. The interview basically consisted of where you wanted to work, what position you wanted, and what you thought the hardest thing for you would be. Very easy. It seemed like they had already made decisions of who they would hire. Everything was very laid back, and it was an enjoyable experience. I wasn't offered the position I wanted however, so I declined.
