Well normally you get headhunted as by the name it is a secret service. But i am not sure about today but you can send an application but you have to meet a very long list of criteria to even be considered of an interview. I think your best bet is learn a foreign language, Arabic, Russian, and Mandarin are very hot in their eyes along with dedication to the U.K. So possibly serving in the military for a few years or in some government position shows loyalty. But the rest is mainly steer out of trouble don't get involved in dodgy activity have a good bank record and you never know!
the MI6 was built in 2004
We have the CIA The British have MI6
MI6 is the British Secret Intelligence Service responsible for intelligence and security operations overseas. There is no separate division specifically for children or kids within MI6.
Criminal Justice would be good. A military background would be beneficial.
MI5 is domestic intelligence while MI6 works overseas
No
MI6 (the British Military Intelligence) agency is always spelled with capitals.
