Northrop Grumman Senior Developer interview questions

The interview was organized but very friendly. Since I'm from the area, there was quite a bit of smalltalk about the part of town I live in and my rehab of an old Victorian home I bought in a historic district. Other than that, the interview style was fairly laid-back, asking questions about the types of projects I had worked on at my previous company and how, specifically, I used some of my IT skills. They also asked some very specific questions about my knowledge of database theory -- describe the various types of joins, for instance.
