They are no good explanation of how to choose a career as a spy, but there are generally speaking two variants, cpu temp one military and the other by the police. If you wish to make a career cpu temp in the Foreign Service is enough defense the way to go, perhaps in combination with some relevant training, such as political science or language, or perhaps even better diplomacy.
When it comes to pure spy working as such is probably not something you can educate themselves, or search. It is certainly possible to submit an unsolicited application to the State Department or military high command, but when Norway officially not make use of spies and secret agents, it is unlikely to get an answer. Then it may be easier with the CIA, FBI and MI6 since those searching for employees once in a while, but the cracks for all to be considered is reportedly cpu temp extremely cramped, but this is not known with certainty, because none of them naturally probably says something about anything about either who or where someone is employed.
A second, and somewhat more uncertain way to do it is to make a career in diplomacy or international trade, and then hope some agents of foreign powers trying to recruit you. If it happens, way short of you being attempted commission cpu temp as a double agent or counter-spy, but probably this is perhaps a somewhat uncertain way to get to spy on.
If you want one domestic service, one should first seek an education in the military, then do the equivalent of the police. This would provide access to internal job postings in police surveillance, where such is advertised periodically. But here's the cracks terribly tight, but not impossible.
