Amazon Senior Manager interview questions

Clear interview process that recruitment manager explained in detail, including compensation. I thought I did well aside from one other senior manager who didn’t click with me (he just asked me a central problem to his job and knocked down my first 3 answers, couldn’t come up with more). Didn’t get the offer even though the hiring manager seemed to like me. Was annoyed that there was no feedback given at all, despite all the hours spent interviewing.
