When in Norway? -By using their native language, norwegian.
When elsewhere?- Every norwegian recieves an education in english spanning over at least 10 years, but most have it as a subject for a couple of more years, just for good measure (but all starting at their first year in scool, at the age of 6).
Hence English will be the norwegian mans prime choice of foreign language, when faced with a situation that demands it.
Most also have a third language, like spanish, french or german. This is studied either 3 or 5 years, depending on how devoted the student feels to the subject, and starts at the age of 14.
So all norwegians are given the opportunity of speaking and writing near flawless english, and have at the very least adequate proficiency with one or more foreign languages, but of course: talent varies with people.
The most common pit norwegians tend to fall into when it comes to bad english, is BAD intonation, in other words: speaking english, with a completely norwegian intonation. Describing this with words is far more difficult than merely pointing you to YouTube, and have you listen to some random norwegian.
Hope this helps as a general answer to a somewhat vague question ;P
(not Denmark or sweeden, as the three pretty much understand each others languages)
I didn't understand the question so well, but I'll try to answer it.
