My biggest complaint is the commute into Hartford which has nothing to do with the company, but should be a consideration.
While the building is nice it is in an area that is slowly being built up so while there are a few lunch places and a great food truck, you have to drive if you want something different. In a few years I see this problem going away hopefully.
The company has had some previous struggles which are well documented here on Glassdoor, personally I am not seeing any of this, but it almost made me pass up the interview. I even brought this up during the interview and was very frank with everyone I interviewed with.
The interview process can be a bit long and tedious as you interview with various groups, projects tend to be siloed so it may take multiple interviews to find the correct fit.
