I took the quiz online. I did pretty well on it and I would go straight to the 2 hours technical interview. The process is well defined and everything about the interview goes the same with what they have on the study guide.

2.5 hour comprehensive interview. Split between a live coding test to build a simple web app based on a mockup, and some technical and design questions. They are professional and give feedback in a follow up email, but expect to prepare for a broad range of topics in the technical questions part.
