Vantaggi
Great company to work for. Perks are amazing. Challenging work. Smart people. It's a well oiled machine for a company of its size and has been working to address the *systematic* internal issues (eg developer productivity). Overall it's hard to beat.
Svantaggi
The company has been bleeding culture as the old timers leave and the hiring process is slanted towards what have been described fairly accurately as "worker bees from Google." In general, I saw my newer coworkers were smarter but less fun than the older ones. Recently there has been a lot of turnover at the company in what is basically a systematic sweeping of house as they look for people internally who aren't up to par. This is concerning even for those above this bar, although I can understand that it may make the company stronger long-term. Not enough upward mobility. Promotion/feedback process can be gamed.
