Northrop Grumman interview questions

Filled out their application online, contacted by a recruiter the next day asking me to fill out a questionnaire. Couple days later, the recruiter emailed me again to see when I am available for an on-site interview. Since I live about 4 hours away (by car) from the interview site, the recruiter was accommodating and allowed me to change my original interview time, but NG didn't help with the relocation, so I had to spend my own money on gas. After i arrived at the interview site, I checked in with the security and waited for the project manager, who was at least 10 minutes LATE for our scheduled interview. It was unprofessional and I was not impressed, but I thought the interview itself went well until the very end when the manager revealed that she has other candidates on her mind, by then I knew I wasn't going to get the position.
