Amazon Web Services interview questions

Describe a project that you really enjoyed working on.

Behavioral questions on Amazon LP, live coding. The interview was professional and a good experience overall. What was unsatisfactory was the follow-up. I've read many examples where AWS would provide feedback even when a candidate is rejected, but the recruiter only said they cannot provide feedback due to "privacy policy". Even though this email stated that I could let them know if I have any questions, when I asked exactly what is preventing providing feedback, I never got a reply, which was very unprofessional. I was only asking for feedback for future improvements, especially since the interviews felt quite good from my perspective, and the interviewers responded well to my answers. With this, it felt that there was no justifiable reasons to not provide feedback & reject me. In addition, I also read from many posts that Amazon's grace periods of re-application is 6 months for many positions, but for some reason this position's is also 12 months.
