First round interview was stressful, and involved a few brain teasers and basic conceptual questions. I have listed them in the interview questions section. It took about a week to get a response from my recruiter. I highly recommend going to a information session at your university before the interview, and introducing yourself to your recruiter this had a huge positive in my column. The second round interview took place in Oklahoma City for me, there where 15 other students from across the US, we flew into OKC the first afternoon where we started by doing some team-building exercises, presented a slide set with our groups that we had to prepare before attending the interview, and then listened to a presentation by some employees. This process took until around 3 am. We started the next morning at 7 am, and went to a job site to see a full scale of what one of the subsections looked like. We came back to the hotel for exit interviews, upon everyone completing their interviews we went to dinner and where released from the interview around 9. People who drove where free to go home, most of us went to a bar in town and hung out. The next morning you take your flight back to your original location, some flights where as early as 5 am.
