Lovely office, lovely co-workers! Lots of flexibility to carve out the path you want - it's really what you make of it. I enjoy coming to work, and appreciate not being micromanaged. Exciting environment for those who don't need rigid structure to get the job done.
Cons
Communication can often feel disorganized, especially with international teams. I've seen great improvement over the past 5+ years, but there is always room to grow.
