Pros
When I joined the job seemed like an interesting job. However, soon it turned out that the group where I worked had hardly sales. I didn't find real pros. Probably I didn't see the good sides, because they must be there. But not in Italy.
Cons
In Italy it depends on the network you have. Skills are not the only thing that counts. One symptom was that in Agrate very few job openings were posted on the internal website (all organized in the network) , whereas in Grenoble often many jobs were posted. The sites are comparable in size. People / management doesn't keep promises and not the right people are in the right position. Colleagues were also not willing to share a lot of info with other colleagues in an order to 'be important'. For example, software was not commented so that others would not understand. I had a few employers, but ST was by far the worst.
