Amazon Manager Human Resources interview questions

After an exceptionally long process. Final process was 4 hrs long with 8 interviewers, I was told I was successful, but the role no longer existed. They said I would however be considered for any other roles for the next 6 months. There is no telephone number for any recruiters. They ignore emails. You give of your time and energy and no respect or communications is given back. Next thing I got an email saying I was successful, not long after I finally got told they thought they had a role for me.
