Avantages
Being a consultant you learn a lot. You work hands on with projects and gain experience that is hard to obtain otherwise. You learn how to combine personal skills such as communication skills with technical abilities. A lot of young faces in the company and good people that like their jobs.
Inconvénients
They used to have quite an anachronistic approach on how they run their projects and they did not invest on their employees. Most of the employees flee the company after they gained experience which is really bad for the company itself. The senior consultants do not have a prestigeless mentality which I believe is uncommon for a Swedish company. There are many other consulting companies that have outrun them by miles in terms of managing employees. internal procedures, running projects, investing in technologies etc
