Amazon Senior Project Manager interview questions

The interviewer asked only one LP question in the phone interview round for entire 60 mins which went really well but didn’t get invited to loop round. The interview didn’t even have time to answer questions back.

Screening by hiring manager followed by call with recruiter then final loop of 5 back to back 1 hour interviews. Very unprofessional throughout the entire process. The recruiter asked me if I think I can pass background checks if extended an offer? As if they thought I were some kind of criminal? And then the recruiter also discussed a way below market salary range and said if I didn't agree to that salary, they'd cancel the final interview loop. Multiple interviewers were over 10 minutes late during the final loop which demonstrates a lack of respect. Then after all of that time, they sent a generic email rejecting me several weeks later despite having a 5 day SLA.
