Northrop Grumman interview questions

They called me and acted as if I had made a previous commitment to fly there and interview, as if they had talked with me before. They hadn't. I flew there the next week. I arrived at 8, I was given a schedule and was interviewed by HR and several managers and given a lunch ticket for the cafeteria during lunch. The building was huge and I had to be escorted from place to place. I ended the day at HR and they made me a verbal offer, which I said I would consider. They paid for airfare, hotel and car. I flew home the next day, my offer letter came in the mail within a week and I declined due to insufficient salary.
