Pros
Very open and "start up" environment. The team truly works as a team. You see individuals interacts with each other throughout the day. People are willing to help each other aiming at the common goal - complete the sprint or the project on time with high quality! People on the tech team are very smart, some are brilliant. The leadership here is also very strong. I never felt lost in a project. Our VP has built and sold start up company himself.
The tools provided to developers are top-notch. The Atlassian suite was implemented last year and had a hug impact to the productivity to the team. Management has been very open to new technologies and new ways of doing things.
Cons
the company isn't a start up, although for certain areas in the firm it still has the start up feel. You won't get company stocks just by being there. You have to work hard to get it, in form of stock options. I believe 2 years of working full time will make you eligible. Then your performance will have to be really good.
