Amazon Applied Scientist interview questions

Interviewed for an applied scientist position. Failed during the virtual on-site. Had 5 rounds. ML breadth, ML deep dive, interview with the hiring manger, coding, and bar raisers. The initial 3 went relatively well. Couldn't solve the coding problem because it was not actually a pure coding problem. It was a probability/stats problem. 4 interviewers out of 5 had pretty bad accents. It made it even more difficult for me.
