Amazon SDE-intern interview questions

In the first stage, you are asked to debug 7 questions relating to different sorting techniques. this followed by some leetcode medium difficulty for round two. This was the point at which i got rejected

1st round debugging, 2nd round - 2 leetcode style questions, 3rd round- work simulation. Final interview - 2 LP questions and a leetcode easy. They took about a month to schedule my final round. Currently waitlisted. Interviewer was really nice! Overall, not too difficult of an interview.
