Amazon Senior Applied Scientist interview questions

Final interview where I made a presentation and then had several rounds of interviews with different interviewers over the day. In asking questions, the interviewers really stuck with the Amazon method of asking, "Tell me about a time when...," each related to Amazon's Leadership Principle. Some of them asked a question about a different principle than I was told in advance, but overall they were more or less what I was told. I think I answered these leadership questions reasonably, but I stumbled on ML questions and a statistics question in a package delivery context.
