(2 Questions)
Round duration - 60 Minutes
Round difficulty - Medium
This round was purely based on Data Structures and Algorithms . One has to be fairly comfortable in solving Algorithmic problems to pass this round . Both the questions asked were quite common and luckily I had already prepared them from CodeStudio and LeetCode.
- Q1.
Binary Tree Traversals Problem Statement
Given a Binary Tree with 'N' nodes, where each node holds an integer value, your task is to compute the In-Order, Pre-Order, and Post-Order traversals of the binar...
- Ans.
Compute the In-Order, Pre-Order, and Post-Order traversals of a Binary Tree given in level-order format.
Implement functions to perform In-Order, Pre-Order, and Post-Order traversals of a Binary Tree.
Use level-order input to construct the Binary Tree.
Traverse the Binary Tree recursively to generate the required traversals.
Ensure proper handling of null nodes represented by -1 in the input.
Return the three traversals as
- Q2.
Reverse Linked List Problem Statement
Given a Singly Linked List of integers, your task is to reverse the Linked List by altering the links between the nodes.
Input:
The first line of input is an intege... - Ans.
Reverse a singly linked list by altering the links between nodes.
Iterate through the linked list and reverse the links between nodes
Use three pointers to keep track of the current, previous, and next nodes
Update the links between nodes to reverse the list
Return the head of the reversed linked list
(1 Question)
Round duration - 45 Minutes
Round difficulty - Medium
This round basically tested some concepts from Data Structures and File Manipulation .
- Q1.

- Ans.
The problem involves finding the intersection of two sorted arrays efficiently.
Use two pointers to iterate through both arrays simultaneously.
Compare elements at the pointers and move the pointers accordingly.
Handle cases where elements are equal and update the intersection array.
Return the intersection array as the result.

- Q1. Given a Linked list , print yes if it is palindrome else print no
- Q2. Print the level order traversal of the binary tree in the spiral form
- Ans.
Print the level order traversal of binary tree in spiral form
Perform level order traversal of the binary tree
Alternate the direction of traversal for each level
Use a stack to reverse the order of nodes in each level
Print the nodes in the order of traversal
- Q3. Maximum of all subarrays of size k(Expected Time Complexity O(N). Input : arr[] = {1, 2, 3, 1, 4, 5, 2, 3, 6} k = 3 Output : 3 3 4 5 5 5 6
- Ans.
Find the maximum element in each subarray of size k in a given array.
Iterate through the array from index 0 to n-k.
For each subarray of size k, find the maximum element.
Store the maximum elements in a separate array.
Return the array of maximum elements.
- Q4. Given Two sorted array of size size n each. Find the Kth largest element in these two array (Expected Time Complexity Log(n))
- Ans.
To find the Kth largest element in two sorted arrays, we can use the merge step of merge sort algorithm.
Merge the two arrays into a single sorted array using a modified merge sort algorithm.
Return the Kth element from the merged array.
- Q5. Website having several web-pages. And also there are lot many user who are accessing the web-site. say user 1 has access pattern : x->y->z->a->b->c->d->e->f user 2 has access pattern : z->a->b->c->d user 3...

- Ans.
Merge two sorted arrays into one sorted array with expected time complexity of (m+n).
Use a two-pointer approach to compare elements from both arrays and merge them into the first array.
Start comparing elements from the end of both arrays and place the larger element at the end of the first array.
Continue this process until all elements from the second array are merged into the first array.

Interview Preparation Tips
Experience: Just 1 online test
Round - I (90 mins)
Online Test conducted @ HackerRank
a. M.C.Qs (Operating System + Aptitude + C Programming Language + Object Oriented Programming)
b. Programming (2 coding questions)The Online Exam started off after a brief Presentation on Amazon.
The MCQs were largely based on Operating System, Data structures and Algorithms, OOP concepts, C language and Aptitude.
Coding Questions
1. Determine whether a Linked List is a palindrome or not.
2. Given few sets of intervals print out the the entire intervals without overlapping , if they overlap then combine them into one.
Eg: Input : (5,7) (1 , 6) (2 ,4) (10 ,14) (8,9)
Output : (1,7) (8,9) (10,14)
Advice: Must solve at least 1 coding question to have a good chance for selection into the next round
Tips: CGPA holds importance because it is basic eligibility criteria for written test and then secondly it increases odds in your favor of your selection more than those with lower CGPA with same interview performance. Prepare a good resume
1. Prioritize your content
2. Put the most important information first (Academic Projects + Internship)
3. Proofread it twice
Advice : Do your best and leave the rest to god
Round: Test
Experience: Round II
2 Coding questions
1. Classic 2-sum problem
2. Given numbers a, b as the seeds for the Fibonacci sequence determine if a third number 'k' is a part of that sequence or not. (Tricky)
Total Questions: 2
Round: Other Interview
Experience: Round III
1. Tell me about yourself
2. Project + Internship Discussion
3. Compress a given string "aabbbccc" to "a2b3c3"
constraint: inplace compression, no extra space to be used
assumption : output size will not exceed input size
Round: Technical Interview
Experience: Round IV
1. Internship Project Discussion (30 mins)
2. Find the largest count of 0s in a row in a matrix of 0s and 1s sorted in an ascending order row-wise.
3. Replicate a tree with random pointers inplace
Round: Other Interview
Experience: Round V
1. Question related to graphs involving concepts of Depth and Height of a tree. (Took a lot of time in solving it ! but finally recognized the pattern)
2. Maximum size square sub-matrix with all 1s
3. Find the median of an infinite series of integers
4. Find the most popular Google searches. (solved it using Trie and Max-Heaps)
2 more questions but can't remember them.Finally after waiting for more than 9 hours the results were announced and I was selected
Tips: Be cool and always ask the interviewer questions at the end of the interview. Explain the interviewer your progress while solving the question so that you both are on the same page + its easier for him to understand. Behavioral and H.R.
Tips
1. Speak clearly and with confidence
2. Always prepare yourself beforehand for some common questions like:
a. Tell me about yourself.
b. Why should I hire you?
c. What are your strengths and weaknesses? (give examples)
d. What is your Dream Company?
General Tips: They judge you purely on the basis of your knowledge and performance during the face to face interviews. The extra curricular activities are not given much consideration as Amazon focuses its recruitment procedure purely on the basis of your Technical Knowledge. Prepare a good resume
