I almost signed at a software company working with interesting maintenance optimization for big machines, like trains or helicopters. Up until the final meeting with the CEO, I was promised that I could stay out of the military applications. But the CEO luckily told me that actually I could not be avoid those applications. So I politely said that I would being declining the offer and that I was disappointed that lower staffs and bosses mislead me.
