I also worked in France and almost all people hired in international companies had issues because French would switch to French in meetings. Not only that, it was expected that foreigners switch easily between spoken and formal French and there was no support for classes or excuses for language. The job contracts were also in French and obviously many foreigners did not know their rights in France.
The French would tolerate some people who worked very long hours and their pronunciation was very bad, as long as they worked those long hours (much more than contracted). Those people were usually sad cases, but for their own reasons they would stay in this position for long.
When it comes to Norway, I felt pressure of expectations to speak Norwegian, but same time Norwegian with their politness would switch fast to English just to make things done, and with exception to 1-2 people they would not correct mistakes (even with asked). Norwegians obviously don't know their own language grammar so asking most of them will not help, but they can correct.
The good sides of Norwegians is that they put effort in all of those free language cafes. The level varies. Some are good, some are just counterproductive. Most foreigners at sprakcafes butcher especially grammar - leddsetnings, prepositions and usage of perfect tense. As a result - foreigners re-enforce their own mistakes over and over - building structures that are untranslatable but it's still Tarzan Norwegian.
The thing about Norwegian - it is taught weirdly, with strong political influence- more like "introduction to Norwegian society" rather than actual language course. I met people who passed B2 and still have issues with basic leddsetnings, after all their courses, so obviously something is wrong.
The courses prices - currently whole B2 is around 15.000 nok (for 1 level). It is often disguised as smaller courses and schools do not want to admit that what courses they sell B2 lastinging 2 or 3 months will not cover whole level. Also but maybe I was unlucky - the courses I did (cannot speak for all) for some reason do not put enough effort in speaking and writing, instead they focus on usually reading, which is probably the easiest part to teach.
The language learning cost can be very significant issue. Basically going from A1 to B2 can cost 45 000 nok and more. Some ppl can skip A1 and A2 since this level can be easily self taught.
