Pros
The pay is probably about 20% more than you'll find in other similar companies. The benefits are better than most other companies, too. The people are all very professional, extremely intelligent and good at their jobs.
Cons
Leadership is almost always hypocritical saying that they value their employees, but they really value the company's P&L more than anything. There are a lot of pockets of cliques. Too many people have so much individual pride that it sometimes gets in the way of them doing their job correctly. The compensation system is VERY complicated and large. Everything takes about an hour to accomplish. There are SO many systems that have to talk to other systems so that something is always breaking then being fixed. There are at least 3 main billing systems alone. Simplifying processes are clearly not a priority to upper management. There isn't a lot of coordination between groups (marketing, finance, operations). It feels like a bottom up organization process.
