Amazon Software Engineer Internship interview questions

Interviewer was nice.Lots of behavior questions. Refer to the Amazon 14 leadership principles is good for preparing. Coding problem is not hard, but lot of corner cases. Good Interview experience.

So I applied for Summer 2019 Internship position. The process took more than 3 weeks and consist of 3 rounds. The first round consists of 7 debugging questions and quantitative question. The second round was coding round with 2 coding questions one related to array and other was related to n-ary tree to be completed in 70 mins. The final round was Interview round of 45 mins. It was a phone interview where they asked me 3 behavioral questions and one technical question. It was tough. One can crack it if they have a very strong knowledge of data structure and extremely good in coding
