Pros
First, I will say I'm not out of the Dayton Office, Im at a satellite office, but Glassdoor doesn't give the option to not say where you're located. Seriously I have worked for a lot of consulting firms and SO FAR I have been VERY happy with Sogeti. My unit at least is VERY good with promoting their people, I've even had to turn away promotions. Our VP is awesome, supports a lot of your ventures. Granted Im not a "company man" you cant be in consulting but if you have to go some place my unit is great!
Cons
I will say that there are offices that just do not pull their weight. One that comes to mind is the NYC office. Very smart guys are being held down by a director that is a white paper regurgitatior and really has no working knowledge of the products he pushes. He often royally messes up projects.
