Took the OA (got a perfect score) and then a week later, got the scheduling invite for the final round interview. Final round interview had two portions: around 4 behavioural questions and 1 technical question with lots of follow-up questions. Make sure to study LPs for Amazon, I was able to do the technical part perfectly (a matrix question involving DFS), but I didn't really incorporate much of their LPs into my behavioural answers which negatively affected my candidacy.
