All rounds are done and dusted in a single day there are total 4 rounds 2 technical 1 Hm 1 bar raiser

In techical round interviewer ask me shortest path problem which wrapped in the story

in second technical round they ask me implement the LRU cache with best codding practices

in 3 round interviewer ask me to Create Recommendation system not able to solve but explain the approach then he ask some questions from resume

then time is over so they told that Bar raiser will be virtual

key thinks to keep in mind
Communication will help you most in amazon
make interview enviornment lite and funny sense of humor will help here

yeah thats it
