Pros
High reputation in Finland. everyone knows (and respects) it. I believe, in some fields, they do high-quality research.
Cons
I must say that in some fields, the quality of their research is surprisingly low. Some of the managers were very, very inexperienced and arrogant, with a low-level knowledge of the field. The top management team seems to choose "team leaders" without enough understanding of how good they are... (which is terrible) All employees have to register their work-times every day, and each meeting has to be shorter than X mins (45 or 60), hindering good researchers from having proper deep discussions. So, it could be good for those who want to be employed by a well-recognized organization and pretend to be a researcher, but really not good at all for research-minded people. I also add that the salary is not good, and benefits are not good at all. The other thing is that, even though they claim to be international and diversified, it is just a "Finnish company". Too Finnish.
