Amazon Developer Senior interview questions

2 telephonic and 7 face to face (same day). focused on resume and what you did is the key. They will ask almost everything but don't lie or bluff. lie can fetch you job but that is not stable

I had a telephonic interview with Amazon and was asked a couple of questions. 1. Given an array of numbers (+ve , -ve) and a number k, return true if any two numbers sum up to k. This question tests datastructure (Hashmap) and BST knowledge. 2. Design an online airline reservation system.
