The interview was really laid back, at least for me. I interviewed with two professionals, both asked me more behavioral questions than technical. Then again, I have alot of technical experience that I provided for them to reference on my resume. They asked me questions, wrote down my responses. I took opportunities to ask them questions about the work environment, etc., to which they were more than happy and excited to answer. Really, because of the nature of their work, they can't go into detail about what you will be doing, nor will you be able to get a good response when you ask about it. Your best bet is to do a lot of online research about the NSA before you consider this job.
