A number of executives came from Kiva (now Amazon Robotics) so they do have Amazon hiring DNA in their process. Typical phone screening is first step, once you have passed that they will bring you in for 5-6 interviews across a cross function group. It is long day but questions are your typical sales questions and helpful to have discussion beyond sales team e.g deployment, product, engineering etc. Once you have completed interview, the team gathers at end of day and provides recommendation of hire or no hire.
