    Interview Experience
     This interview was also HR cum technical round but it was known as a bar raiser round. 
    I am not sure how to spell it too. The questions were almost the same as in the 3rd interview 
    with additional questions like  “ how did you react in conflicting situations in four year career ? “.
    This round also ended with technical questions :
    a) Given a doubly linked list where the next pointer is pointed to the next node in 
    that list but the previous pointer is pointing to any random node. I was asked to make a 
    similar list efficiently . [ Simply a xerox of it ]
    b) The second question was a string based traversing and pattern matting type 
    where there were given two strings ‘A’ and ‘B’. 
    I was asked to return true if all the characters in ‘B’ were present in ‘A’ or else 
    return false. I explain many solutions in which he asked me to code for a particular 
    solution and he verified the code by iterating though the test cases. 
    The round ended with few personal questions on experience and my future role. So, I was into 
    Amazon after a week of discussions :)

    • Question 1: Online Test on InterviewStreet:18 MCQs (Normal C loop questions, networking, dbms, os, analytical)2 Coding questions1. Check if an undirected graph is a tree or not.2. Given an array of integers, print the 2 elements with least absolute difference.Interview Rounds:-Round 1:Tell me about yourself.1. Given a matrix(not necessarily square) in which the elements in a row, as well in a column are sorted. Find a given integer in the matrix.Tell the approach. And then code.2. Given a position where a knight is placed on an nXn chessboard. Find the maximum number of knights that can be placed on the board, so that no 2 knights attack each other.Remember that you need to just give the number of knights, not all their positions. I first could arrange ceil(n*n/3) knights. Then he asked me find a better solution. Finally I got to ceil(n*n/2). Then he asked me to code it. Then he asked me to remove the ceil condition(check for even and odd separately).He asked me if I had some question for him. I asked \u2013 Amazon strives to be the most costumer centric company on earth. What, as a programmer/developer, do you do to achieve this, because generally, the customer\u2019s problems are an issue for high level managers and planners.Round 2:Started with some questions from my Intern project.1. Given a Binary Tree, replace the data of each node by the sum of data of all its descendent nodes.(Leaf nodes will have 0)2. Given a sorted array of positive integers, find the least missing positive integer. First I gave an O(n) solution. Then he asked me to optimize it. Finally I gave an O(log n) solution.3. Given a stream of numbers, find k random numbers from them. I explained him Reservoir Sampling approach. He asked why this approach works. What is the probability of each number being selected? What is the probability of any number being selected if stream has less than k numbers(its 1).He asked me if I had some question. I said I had one, but I already asked it to previos interviewer. He asked me if I got a satisfactory answer to it. I said the answer was very much satisfactory.Round 3 (CS Round):He asked me if I am comfortable with writing SQL queries. I prefered not to.1. What is an interface? Why it is used? Give an example. What is an abstract class? Why it is used? Give example. Why 2 different concepts of interface and abstract class?2. Do you know about singleton class? What is it? Implement a simple singleton class. I made some mistakes in making attributes static etc. He guided me and finally I corrected all bugs.3. Given a binary tree, where each node has an extra next pointer. Fill the next pointers so that each node\u2019s next pointer points to its next sibling node. First I gave a solution where I would require a map, where each map key will be a level number, and value will be pointer to the last currently accessed node of that level. Then he asked me to do it without space. Finally I gave him a solution without space. I gave a non-recursive approach, and he asked me to code it.Round 4(Senior SDE 3 from Seattle Office):He told me about himself, his team, his work and his team\u2019s work.1. Tell me about one of your challenging project/internship/class assignment.2. Give a situation from your life where you were given a negative feedback, and how did you tackle the situation.3. Explained me a cache situation, where, keys will be in cache, and each key will point to a string. It was LRU cache condition, and I had to implement the LRU cache. Then write a function to retrieve a string, given its key, from this cache. Retrievel should be O(1) (if you give O(n) retrival, he will ask you to make it O(1) ). - asked on Dec, 2013 in Varanasi
