I have a friend who worked for the NSA. We had a heart to heart over drinks about a year ago. She asked what I thought about her working there. I responded, honestly, that if I didn't know her personally I'd be starting to wonder if she was, for whatever reason, unable to pass muster at Google et cetera. Not the best decision to drop that after a day of drinking together. But I'm glad I did--it was apparently the nudge she needed to quit.
Going to work and feeling like you're working on secret, cutting edge kit with the smartest people in the country is tremendously important to many people. The NSA lots its veneer of whiz kids confidentially cracking codes for good with Snowden. It now feels like another federal bureaucracy.
Postscript: She now works in the private sector and is thrilled with how much closer to her intelligence her new colleagues are. If you work for the NSA and are not a numpty, you're selling yourself short.
