All Norwegians become crown millionaires, in oil saving landmark 13 years ago
I work in a norwegian (infosec) company [1] and we have hired several english (only) speaking persons to get the best talents.
Norway have quotas for people with specific skills and it is my understanding that it is not that hard to get a Visa.
I also know several other companies, e.g. Opera Software, are mostly english speaking and most large companies in Norway within Oil&Gas, and Finance have english as a corporate language.
