Great co-workers. No dress code. Free lunch on Mondays. No "A-hole" policy.
Cons
Not much team building outside of work. Office environment can be very quiet and painful sometimes. Very top heavy on the executive side. No room for advancement.
We work a full week like everyone else in the Valley, but I am constantly challenged and given rope (which I sometimes use to hang myself). I'm learning and growing and the people who work here genuinely care about me as a person and my career. They have a "no a**holes" rule which I truly appreciate.
Cons
Well, it's silicon valley, so we work hard. But my weekends are actually mostly mine, so better than most other companies around here. Also, no fooseball.
