Pluspunten
The people are generally nice and pretty smart, which makes working more enjoyable. The managers are generally good and constructive with their criticism, they are also keen to look after you and your career path. Career progression, in my role at least, is very structured and it's easy to tell where you are and where you need to be heading towards. Finally, the upper management are smart and friendly and always interested in hearing your point of view, even if you're very junior.
Minpunten
I feel that in the interests of being fair, management can sometimes lose sight of other issues. There can also be a little arrogance in our department that we are better than the other company departments, which doesn't help the integration push we are having. I think this would be perceived by the other departments too. Feedback can sometimes be too consistently positive, which makes it difficult to know whether you are doing a great job the whole time or your manager is just being nice, it can also make it difficult to know in which direction to move forward.
