The review process is somewhat daunting, but once you get a good hold on the company and its mission it is not too bad. The recruiters (especially in the early rounds) can come off cold, but its because they have a pretty strict script they seem to be sticking to. The process really is to find people that are the right fit for the job.
Interview 1(video interview, not gonna talk about it because so many other reviews do)
Interview 2 (behavioral, know the bread process)
Interview 3 +4 (case + role play. Read the cases on their website, it really is a backwards linkedin search at the heart of it. During the role play, just come off professional and be able to explain what AS does)
Interview 5 (final round, VP. really deep behavioral, be ready to really explain how you align with the position)
