Pros
Great company overall! The CEO truly cares about making the company great and makes himself very visible and has very good demeanor. Benefits are outstanding. People who have worked there long try to make it great as well. You will quickly find that everyone knows what they're talking about from the SVP to the director and most managers. Those people have been around and were engineers themselves. We're definitely at the forefront of the internet and try to make it fast and secure.
Cons
Politics is quickly rearing its ugly head as they hire managers who come from outside. They are usually unproven and insecure about their roles and try to dictate things they don't quite know well. I have seen a couple great engineers leave because they don't get along with them and I think I might be in this situation soon. If you do your job too well, they may start to think you're trying to outshine them so the best thing to do is leave. Fortunately, I think movement between departments might be an option.
