Google's engineering is, on average, passable. Thousands of brand new grads that have studied to pass 5 rounds of interviews and have no experience are only going to put out barely passable software. Hell, the very reason that Go is so simple is because, by Google's own admission, their sw devs can't be trusted with anything more complex.
What you see coming out of Google that may look cool (when it's not a new chat app they'll kill in two years) has thousands of drones behind.
