Vantaggi
Geneca provides a ton of opportunities for those who are looking to grow their skills and learn a diverse set of technologies. I second the previous comments about people generally being open and caring. There doesn't seem to be any politics or game playing. I look forward to going to work each day.
Svantaggi
This is a consulting firm and there are expectations that you will go where the client needs you. That can be anywhere in Chicagoland, up to an hour drive or more. Geneca tries to do most client work in their offices but sometimes you end up at a client and working within their culture, rules, etc. I can tell that most of the negative comments on here are from former employees who were let go. One of the things I like is that most of the employees here are smart and work hard. If you are looking to just loaf along or you can't handle consulting, you'll end up "not being a fit" and quickly moved out.
