Got referred by a friend, passed phone screen. Phone screener asked very specific JavaScript / HTML5 / CSS questions, for domain specific stuff, mostly javascript.
When on site in Palo Alto, had 5 interviews. 1 with hiring manager, 4 with engineer, 1 lunch break. All questions were algorithm questions except for hiring manager which was system design question and 1 behavior question. "What kind of people do you not get along with?"
Interview was pretty stress-free and easy if you know fundamental CSS / JavaScript / HTML / HTTP / back-end and have a strong knowledge of algorithms / data structures.
