Interestingly, I've actually been put forward as an interviewee for two of the companies on the front of the linked page (Gamma + Cobham) by your usual nefarious job agents trying to get anyone in anywhere for a chunk of commission. My speciality is code, data and operational security so I assume they were interested on that basis.<p>The agencies and the companies themselves describe them in a completely different fashion, almost as if they have to hide what they really do to get people interested.<p>I turned both down on the telephone interview stating my objection and why.<p>The agent gave me a face full over it because I embarrassed him to his clients. I told him to pick some better clients.<p>I get the feeling that a lot of these places hide what they do until you get there. The agents will sell you to whoever as well. Watch where you step.
