As SAS are currently on their way to get rid of their 737 fleet in favour of the A320 you donīt have to worry about having to switch to the Boeing - they want and prefer A320 pilots!. The assessment is done on the worst sim I have seen and been in. Itīs a fixed base that feels (and looks) like it was built by a drunk chimp. Entry level salaries are around 3500 EUR before scandinavian tax (about 30%) and they will work you hard (this according to themselves).
Good luck.
