Government Communications HeadQuarters is based in
Cheltenham UK and is the number one listening post for intercepting communications activity all over the world. Run by the
British government, it shares information with the
USA and forms a major part of the
UKUSA Echelon system.
Although frequently referred to as a "spy centre", it is not the HQ for British spies in the James Bond sense of the word (that honour goes to M15 and M16)- instead GCHQ provides and receives the vast bulk of information that spies seek and gather.
GCHQ is constantly recruiting. They have the best computer set-up in the world bar none, and they love nerds and geeks. If you're a British nerd or geek who doesn't have a strong political affiliation, send your CV to Recruitment, GCHQ, Cheltenham, or apply on-line at their official website: http://www.gchq.gov.uk
