1. Phone Screen (typical) 2. Analytics test - math word problems, ten questions, takes about an hour if I remember correctly. The math is high school level probability and stats, but they're mostly testing your ability to approach the problem correctly, from an analytic standpoint 3. Phone screen with hiring manager 4. 4-hour on-site interview with hiring manager, and three senior management, separately. Most of the questions were behavioral in nature and a few "what-if" scenarios, but not really case interview type questions. I also had a few math riddles.
