Hello. I have. The first time, I was offered a job working on missile guidance systems. I told them I would not work on weapons, so they offered me a job working on something else instead. Then they asked me to move to another project that would require getting government security clearance. I said I wouldn't do that either because I was not willing to make the required promises to my government, so they gave me other projects that didn't require it. It's really not that hard to have a penny's worth of a moral compass if your skill has any kind of value. I think maybe the problem is people who only have value to companies that only hire people without any morals.
