Pros
The people I work with are fun & smart. And you can't really ask for anything better than that. I've always said, I don't care what I do as long as it's with good people. But I also get the benefit of loving what I actually do. The benefits rock. Obvi. It's worth mentioning, but I feel like everyone mentions it... so boooooring. I've been here for almost 3 years and as the company matures, it has really only gotten better. All the best stuff stayed the same (the company's commitment to and support of their employees, their commitment to education and our customers, the culture) and the stuff that had to change for a company to grow (processes) has been pretty painless, lean and smart.
Cons
I work in a department that was sorta in rough shape when I arrived (Product). That reputation preceded us in the local community. That makes it a little tough sometimes when talking with folks outside the company... but hopefully, the turn-around we've had over the last year will seep out into the local community soon. Because Product is basically rock star status now. I think the people who needed to leave left and the right people stayed.
