An initial meeting followed by a 4 hour on site code challenge followed by a final interview with a senior engineer. The code challenge wan't too challenging, it was a good gauge of programming skills. Everyone on the team was very friendly. Good vibes all around.

Met with 5 engineers over a 3 hour period. Each asked a few technical questions and asked me to code the answers on a whiteboard. Overall, every question that was asked was very fair and each interviewer was happy to help if I got stuck at any point.
