The process starts with a basic phone screen to check your background and why you want to work for the company. You get a fairly short take home from Hacker Rank and a skype call to check your coding ability. Lastly you get the on-site interview. They bring you in and have a fellow Yelper eat lunch with you and chat. Sometimes they will have a 1 hour seminar on a random thing someone wants to lecture about in the company (I've heard it can be about wine tasting, astronomy, etc.) and mine was on Tableau software. The process has you do 4 1-hour interviews with white boarding. If you're a fairly strong coder with some knowledge on machine learning and algorithms you should do fine during the process.

The interviewer is from spam group, so all the questions are related to how to detect spams. Mainly basic machine learning concepts covering deriving features, building simple models, short answered technical questions, and finally there is a coding question, which is about given a n by n matrix, finding the minimal cost from the top left corner to the right bottom corner, the follow-up question is instead of finding just the cost, you are asked to find out the path.
