Georgia Tech Research Institute Student Research Assistant interview questions

I interviewed here and we setup and interview for one afternoon. The interviews lasted about 3 hours and consisted of 4 informal interviews. My interviewers were really pleasant, I met with the head of the department then with 3 different engineers. Everyone was friendly and just explained to me what they did, and how I might fit into the work they were working on. They also asked me detailed and relevant questions based on my resume. The culture there is a little bit closed. Most doors I walked past were closed, but nothing I shocking. Most people seemed to work in labs not actually in their offices.
