Amazon Operations Manager interview questions

It was a very long process. Once passing online screening, skill test which took 90 minutes. Then interview that lasted almost 4 hours with 4 different people. I wish it resulted in an offer.

I've been contacted from an HR, then I got my first interview that was on their own platform. I met three managers in three different stages of interview. The reason I didn't appreciate their policy is that for the first time in my life I didn't pass an interview, I asked a feedback from the HR, to improve for the next interview, but they don't give feedbacks fro Company Policy
