Vantaggi
People are treated very well here. There is a convivial atmosphere, most managers take a hands off/supportive role and there are many opportunities to learn. In many ways, you are your own boss and while that unstructured approach may not work for everyone, self-starters will love it.
Svantaggi
Career advancement can be difficult. It often feels like the same people get promoted over and over again while other people languish at their positions for years, despite being qualified and highly capable of doing more. Also, since the Google purchase, things feel more chaotic and less polished. Managers are busy drinking the kool-aid and jockeying for position so they pay even less attention to their staffs.
