Amazon Applied Scientist interview questions

Get contacted by a university recruiter via INFORMS annual meeting. Submitted application on Amazon careers. I got two one-hour phone interviews scheduled for an Applied scientist summer intern. The recruiter sent me a guide manual about the 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.
