Pros
An incredibly responsive IT department gives you quick and effective access to the tools you'll need to excel in your workspace. The building is a comfortable space to be in in a physical sense, and all of the employees here seem more or less satisfied with their jobs here. Further, the company is experiencing growth in a number of departments, which means that there is always "extra credit" to accomplish if you want to stand out and climb the ladder, so-to-speak.
Cons
The employee parking in the back of the building is a 5-10 minute walk from the doors depending on how much you hustle, so you have to make sure you keep that in mind when planning an arrival time. Some of the bigger players are real "old Hollywood" types and can be abrasive.
