General Dynamics Land Systems Human Resources - Project Management interview questions

It took forever to get through the check in process in the front lobby so arrive early. I interviewed with three people and the atmosphere was very relaxed. They didn't seem to have a set of prepared questions and asked the usual "what is your greatest weakness" and "where do you see yourself in 5 years." They asked about my background, how I build a team and asked for an example of a difficult project and how I managed it.
