Pretty easy, asked a backtracking question and was willing to help out throughout the coding process, rest of the interview was behavioral asking about projects I did in the past.

Applied in Oct, got an OA in mid Dec, and an interview afterward in late Jan, and interviewed in early Feb. The interviewer was nice. 1-hour interview: technical at the beginning (2 questions: graph & 2D matrix) and behavioral (Amazon Leadership Principles) at the end.
