A lot of interesting people, most of them are very competent, and for others, you're wondering how they came to work there. Good benefits, good work-life balance, and it gives a lot of freedom to choose what to work on, with fair compensation.

The performance review system is subjective, which is in fact the case in the whole US, starting from school. Promotions are often given based on friendships, something I thought to be specific to more Eastern worlds.

Promote more transparency into the system.
