Pros
The salary is competitive and I feel the company as a whole generally cares about the welfare of its employees & treats them well. The benefits are pretty good compared to all the other companies I've worked for previously. ESPP, profit sharing, Commuter Checks, software discounts (huge huge discounts on adobe software), company matching on charitable donations, telecommute. onsite fitness center (SJ office). About the only thing missing is onsite childcare benefits (though i don't have children currently)
Cons
The San Jose office is much more conservative than the SF office. This might be in part due to the older age demographic in the SJ office vs SF (I heard it was like 39 median in SJ and early 30s in SF, this was back in '07 -- i am in my mid 30s). Also, it's pretty hard to get decent pay raises once you get in...though that's the same at any large company.
