Hi Stoob and Welcome!
To be honest with you, I have only heared of Holografisk Virtual Reality using C4D. Allso some others which is not that well known.
Im affraid C4D are not much used. By finding norwegian 3D artists from the main norwegian and international forums, we only have about 30 registered users. Not all are using it anymore either.
If the rumours I have heared are correct, 80% of 3D artists in Norway are using 3DSMAX. I find it quite hard to believe it's that high percent scale, but either way it is a very popular app. Second you have Maya. Those two are mainly used here.
The C4D userbase is rappidly growing, though.
C4D are used for industrial design and mograph work.
Good luck finding youself a job!
