Pros
I do like a challenge, and this is pretty unlike anything I've ever done before. From first interview to current assignment, I've worked with nothing but brilliant minds and beautiful souls. My voice counted since day one and I've seen suggestions I made become reality in the first week. Over a year later I'm still constantly asked if anything can be done to make my time here happier or more rewarding. I have many friends jealous of our "you WILL have fun" here culture. We're very "work hard, play hard." There is constant celebrating breaking records as well as just random fun office events to make sure everyone can enjoy each other outside of work, but this all happens because of sometimes long hours and complex files that take a lot of grit to get through. The team support atmosphere and real friendships that come from it are second to none. The hard work is absolutely appreciated and shouted from the rooftops. You'll never see your ideas stolen by upper management and someone else get your credit like some of the horror stories I've heard at other companies.
Cons
Like many others have said, it has hard work and sometimes long hours. Most of us agree that we'd rather have too much work than not enough, but it can be draining at times. It is the nature of the industry, but we have it 100X better than those doing the same at other companies.
