Online assessment 40 minutes, I was looking for some info in order to prepare for the test, and only saw that it was probability dense. The questions themselves really have nothing to do with the probability questions you would expect, its similar to ACT Probability questions, which are not very difficult but definently review the steps to different probability questions because it is a time crunch. Some visual reasoning also, somewhat difficult to follow.

First round had a basic 30 minute conversational interview and a 30 minute technical interview. For the technical interview you're given mental math problems and questions that test your quantitative mindset.
