Johns Hopkins Applied Physics Laboratory interview questions

I applied for this job via University career services. APL contacted me first via e-mail to notify me that my application was received and was being reviewed. I then received a phone call about a month later to schedule an interview date. APL coordinated and paid for transportation and lodging as well as compensated for food and gas for my visit. I flew out the night before the interview and drove to the campus for a full day interview the next day. I had one on one interviews with several members of various business groups throughout the day. At the end of the day, I was asked by HR to rate the groups in terms of interest based on what I had learned. I waited about 1.5 months before receiving a reply from APL that I would be hired. This time, I was contacted by the Group Supervisor of the group that hired me. It took about another month to get me hired. APL offered relocation compensation (they paid it in full) provided that I worked there at least 6 months (or a year? I can't remember exactly).
