Extremely long. They start out with a quick few questions about you (what are your hobbies, etc.) and then a code screen where you have to answer 3 coding questions in google forms. If you make it past that, you have to do another more intensive code interview with engineers on a google doc. You'd think that would be it, but it's only half way. I stopped here, but then they'll give you a take home assignment, followed by more interviews.
