Grueling 5 interviews one after the other. Very formulaic and little conversation. You should look for the person whose job is NOT necessarily part of the role type you are looking for. They are most likely the Bar Raiser and have the most sway over the decision.

Challenging interview process consisting of five separate 45 mins interviews. Amazon's leadership principles are well documented making preparation a straightforward process. If you don't prepare you probably won't do well.
