Amazon Sr. Marketing Manager interview questions

10 people strung out over two weeks. HR confirmed decision date via telephone, and the date came and went. I reached out and again, Ull know tomorrow. Then, a week later an email shows up in my inbox, but with the wrong name. Unprofessional.

Spoke with multiple recruiters, then a phone interview with someone in the same role in a different department -- was very casual. I did a dual interview for two roles simultaneously with a few interviewers specific to a role but most seeming generic. Interviewers were very stonefaced and asked tough questions with plenty of follow-ups. Was not allowed to use the restroom without a "chaperone" waiting at the door which was strange.
