Amazon Sr HR Assistant interview questions

I applied online and was contacted by a recruiter within 2 weeks. The recruiter sent me a pre screening questionnaire. The questions required paragraph like responses and knowledge of amazons leadership principles. After that I was scheduled a phone interview with the SR HR Business Partner. The recruiter thay scheduled the interview said it should last anywhere from 45-60 mins. The call lasted only 13 minutes and only consisted of my experience and 3 questions behavioral questions. These were the questions: tell me about a time you received critical feedback. Tell me about a time you went out of your way for someone and why. Tell me about a process you improved in your current position and why. 2 days later I received a removal from consideration email. The process overall involved a lot of preparation from the material the recruiter sends you to prepare for the phone interview. It seems unnecessary because none of it was useful for the phone interview.
