Amazon Intern - Software Engineer interview questions

There are two rounds back and back. The first round was a guy from 126 and the question was the nth node from the end in a linked list. The second round was a guy from Kindle and the question was reverse a string and lots of fundamental concepts in object oriented programming

Applied online through their website. Contacted me like a month after the application. They told me when i will have two consecutive phone interviews. Did not asked me even if i was available that time. I received an offer two months after the interviews.
