Northrop Grumman interview questions

I applied online, was e-mailed 2 weeks later with a set of screening questions (rather than a phone call). 2 weeks later, I was called for an on-site interview that lasted about 3 hours with the quality manager and 2 quality engineers. It was mostly non-technical, with a couple of very basic technical questions (nothing I would stress over). The interviewer (the manager) was pretty unprofessional, constantly bad-mouthing the organization, and laughing at some of my answers with very "smart alec" sarcastic comments about how that wouldn't work. I found it to be in pretty poor taste. Said they would let me know within 2 weeks, got an email 5 weeks later saying I was no longer being considered.

I heard the panel laughing after I left. The interviewer didnt understand my answer. I felt this was highly unprofessional. I wish they wouldve asked for clarification before we moved on.
