Amazon Software Engineer Senior interview questions

A week after applying to the position, I received an automated e-mail saying that I was invited for a phone interview. This automated e-mail had no information about the interview process, or any information in general. I specifically e-mailed the recruiter that had the contact information in the invitation, and asked for the content of the first interview. I was told that the first interview would be about the Leadership Principles and I should focus on preparing for those. Even though I explicitly asked the content of the first interview, and was told that it would be based on the Leadership principles; they did a technical interview with me. The interviewer even insisted that the information I had about the process is wrong. So to sum up; I was never directly contacted by a recruiter, I was given completely wrong information about the process when I asked, and my interviewer had no clue about the hiring process and did a technical interview even though I was expecting a behavioral interview. I was not even contacted after the interview, and they didn't even reply to the email I sent after the interview in order to ask for clarifications. They really do not consider the applicants as human beings that spend a lot of their free time preparing for this, and they treat them like garbage. I now see that all the similar reviews of Amazon's interview process in Glassdoor are incredibly accurate; and I will never lose time with this company ever again.
