Amazon Interview Experience | 2 months Internship

It was a one-hour technical interview under AmazeWoW program for 2 months internship after the third year. 

First 20 minutes: The interviewer started with asking questions on OOP concepts, revolving around abstraction, polymorphism, inheritance, accessibility of variables. 

After OOP, we moved to Computer networking basics. He asked me about HTTP, https, TCP/IP, different layers(7) in networking.

Next 40 minutes: 

  1. The first question was to do post order traversal of binary tree using a single container. 
  2. The second question was based on array. Given an array of integers, find triplets x, y,z such that all three are elements of the array and x^2 + y^2 = z^2.
