they already have jobs so you have to poach them from where they're working; netflix/facebook/google etc. you do that with money. all this other stuff should be taken for granted. if you're hiring engineers that are failing google interviews then you're not hiring the great ones now are you.
the problem is that most companies don't have the ability to poach great engineers, but they pretend they do so they go and write little posts like this one, but ironically they aren't qualified to be writing these posts in the first place!
