They got a bunch of new questions now so nothing you see on here is that helpful. I was asked a tree problem to rebalance a red black tree and they actually expect running code. System design was something completely unrelated like designing a car dealership management system. People I met was great but I did terrible. They are also heavy on what you do outside of work and seem to prefer people who excels at a hobby. Some employees are professional dancer or compete in some sports or high video game ranking so make sure you sound interesting and have a life outside of work.
