Incase anyone's interested in being a developer at Coinbase, I'll save you some time: they're more interested in pedigree and whiteboard puzzles than science and code. Most disrespectful interview I have ever had in my 13 years of coding, and probably ever will have.
The next problem is that they are still using EventMachine. Still think I'm a crazy person? Oh look, it's like I'm a well-received field expert on this topic or something http://www.slideshare.net/mobile/KyleDrake/hybrid-concurrenc...
