There is two interviews. The first one is the "Life Story" with a recruter and the second one is the Technical interview with two developers. You only get to the second one if you get chosen after the life story. They tell you in advance what it's going to be like and though it's a bit unusual to have to talk to someone who knows absolutely nothing about you (they don't even read your resume), I think it's a good way to get a general vibe from someone and see if they'll fit in the team. The second interview was also very informal. First, they ask you to show a bit of code you made and talk about it, then they present a problem to you and ask you how you'd go about solving it (No code, just talking or whiteboard). Overall it's a fun process and it seems to be more about who you are and how you think than where you come from or what you did before.
