Hola.
The language thingy has to do, among other things with emergency evacuations and such.
Say your King Air is on fire and you have to explain to the little old Norwegian lady how to get out after the landing..Except she don't speak no Espanol or Ingle.
Having been in the seat of the Chief Pilot and having selected C.V.s for pilot positions, I picked candidates with skills such as communicating in the local language in addition to hours and ratings.
That being said, I have also worked in Arab speaking countries without knowing the language, but that was because the local airline had no other choice but to hire foreigners.
Not so in Norway, plenty of warm bodies to fill the seats and in a pinch they hire the odd token Swede or Dane..
