I applied online. The process took 2 weeks. I interviewed at Behance
Interview
The interview starts with working on a dummy app with a lunch break w/ the team in the middle. After that you'll have your code reviewed and a handful shorter interviews with various people on the team. Everyone is nice, though the day is a bit of a marathon (~7 hours onsite), especially considering all of the face to face interviews come after 4 hours spent alone in a conference room working on the dummy app.
