Based on my algorithm here are the 20 most popular questions that were asked during Amazon interviews:

Why Amazon?  
Linked list

What do you do when people say no to you  
on data structures  
Search Tree  
The design problem  
Tell me about a time you used data.  
Tell me a time when you had to design a system?  
find common ancestor in binary tree(Not binary search tree)  
“Tell me about yourself”  
Write a code to find out if a tree is a binary search tree.
