Dutch and Finnish are known for being frank and to the point which is why they are quite well regarded in Sweden. Swedish is more conflict averse, always trying to protect each other and often failing because what happens is that people read in between the lines instead, which is much worse.

disclaimer: I’m Swedish.

I assumed you taught some technical class since this was HN, but if you didn't then I understand since those programs aren't well regarded in Sweden. If it isn't business, medical, law or STEM then it is almost surely ill regarded. I'm not talking badly about those fields in general, just that Sweden doesn't have any good programs for the so the students you get there are really poor.
