Amazon Software Development Manager interview questions

The interview process is straightforward but intense. First interview was with another Software Dev Manager in the same team. After that the famous loop interview where I had to take 5 interviews in a row over two days ( using paid holidays at work ). Recruiter gave a lot of information about possible questions and helped with materials. However, I had to use same stories few times as the different interviewers asked same questions few times. Everything is okay, I had a good time during the interviews and it was a good exercise. However, I simply do not understand why they have to call to reject? I am not a customer to be obsessed with. A straight cut rejection via email works better than taking time out of my busy schedule. If they used this time to share some feedback, that would be useful. If they do not share any reason why I have to continue formal small talk just to get the rejection on my face?
