Amazon Lead Development Representative Leader interview questions

Process: phone interview(based on resume)- Role play 1(interview with role play company CTO/15 min)- Role play 2(product solution presentation/1hr )-Hiring manager interview- HR interview. (I only get through to Role play 2) It's a role play interview that require a lot of technical skills. (more like a solution architect in sales role) I was provided with the information that an Internet Company is considered switching to AWS, and I have to perform a presentation to close the deal. -Role play 1: to get information about client current SPEC. (After first role play interview, I got one weeks to prepare for my final presentation. ) -Role play 2: based on the information i got previously, I prepare a presentation with a) Why AWS? b)Current situation c)AWS solution and product. The presentation was very intense, interviewers would ask questions during the presentation. The questions include lots of technical parts, ie. network problems, how products work..... have to be VERY familiar with AWS products(EC2/EBS/S3/VPC/RDS/ELB/Cloudfront) I answered like 2-3 questions wrong( out of like 15 questions) and I didn't pass this round. The interview feedback is I got very good sales skills but need to improve my technical skills. I would say this is an interview require 10% sales skills and 90% technical skills/product knowledge. I was heard that objection handling is very important but it's really about how deep and how wide you know about AWS products.
