American Express Interview Experience for Internship - EDA/CFR (On-Campus)

Round 1 (Online Test): Consisted of 60 MCQs related to Aptitude, Verbal, Code output and debugging, SQL queries, and finally 2 coding questions that ran very well using brute force. All test cases passed.

Out of around 280 students, 5 students cleared the round 1. I was one of them.

Round 2 (Interview): Honestly, the interview process was very casually taken forward, which is why I had all 3 rounds of my interview together in a total of around 45-50 minutes. The interview was taken on the CISCO Webex platform. There were 2 panelists – one tech and another HR.

First, they asked, “Tell me something about yourself?”. Then they started with the resume questioning. They asked thoroughly about my projects. I had done one related to NLP, so they asked me about machine learning and NLP and basic definition questions like confusion matrix, precision-recall, 3 types of machine learning, etc.

Then they asked me one really simple programming question related to strings which goes like given a string like “This/t/t is a /t/t/t/t sentence/t/t/t” convert all the “/t” sequences to a single “/t”. I solved it obviously. But it was my first ever interview and I wasn’t aware that you are supposed to think out loud. So I just kept typing without speaking and the interviewers got bored.

Microsoft Interview Experience | On-Campus for Internship

Round 1: Online Coding Test

I was in my T.Y. B.Tech. (Sem 5), when Microsoft visited our campus for offering 2 months summer internship.

First Round was online coding test on CoCubes Platform. Difficulty level of questions were easy to medium. 3 Coding questions were to be solved. Questions Were

1. A Number plate problem where only odd and even number plate vehicles can go out on a weekday. Given numbers of vehicle and schedule of odd/even on weekday, find maximum number of vehicles that can go out on a day.
2. A problem based on BFS of Graph. Similar to Rotten Oranges Problem.
3. Given a Singly Linked List, Reverse the linked list in place using O(1) space.

Some Other Questions were

1. Reverse a Linked List in groups of size K
2. Some traversal problem based on BST and graph.

Nearly 25 students passed this round.

Round 2: On Paper Coding Round

Groups were formed and each group was assigned a mentor. We were supposed to explain the approach of problems given to our mentor and code on paper. Questions Were :

1. Check if a given Binary tree is a BST without using extra space.
2. Finding second maximum element of the array.
3. Find Depth of BST.

I found inorder traversal of the tree for first problem but no extra space was to be used. I reduced the space complexity to O(1) but time complexity was O(n). I found depth of BST using Recursion.

Nearly 15 students were selected for Face to Face interviews. I was one of them.

Round 3: Face to Face Interview – 1

Questions asked during my interview were :

1. Write on paper code for Binary Search
2. Implement a Queue data structure using Stack data structure.
3. Write a code to heapify a array. It was basically a Heap Data Structure problem but I messed up here.
4. Asked about Dynamic Programming and a question to find longest palindromic subsequence.
5. ACID property of DBMS.

Only 5 people cleared this round and I was rejected after this.

Nokia Interview Experience | On-Campus for Internship 2021

**Round 1:**It was an amcat exam with aptitude, logical reasoning, and verbal question 2 simple coding questions are asked from arrays concept.

**Round 2:**It was a technical round question asked from my project and few samples code are asked to write in python as it was in my resume and few concepts are discussed on core concepts like os and DBMS

**Round 3:**This round was a combination of HR and technical, I was asked about real-time application of famous data structures like trees, graph, hashmaps, etc, in-depth questions on computer networks

Tip: Be confident and you can easily crack the interview, most of interviewers are friendly and they will help you if you stuck at a point.

Salesforce Interview Experience | SDE Intern (On Campus)

**Round 1:**It was an online test on HackerRank. It consisted of 10 MCQs based on Data structures, algorithms, Operating System and some output based questions and 2 Coding Questions. Difficulty level for this was easy-medium .

Coding questions asked were:

1. Lexicographically next permutation of a given string .                                         https://www.geeksforgeeks.org/find-the-next-lexicographically-greater-word-t
2. A simple hashing question which could have been done using hash-map .

I was able to clear this round . 117 students appeared for round 1 out of which 11 were selected for round 2 . Both the coding questions were easy so selection was dependent on who solved more MCQs correctly .

**Round 2:**This was a F2F Technical Interview or I’d say more of a problem solving round. Interviewer seemed friendly. He started off by asking about myself, then after giving him introduction and straight away jumped to DS and Algo.

1. You are given co-ordinates(all different initially) of racers on x-axis and a final destination on x-axis . All racers will run towards destination . Speed of every racer is given . So while running some racers will come side by side so they will form a group and will start running together with speed of slower one. Further clarifying he said suppose there are 2 groups, one with 4 racers and one with 2 racers so they will form a larger group of 6 racers if they come side by side and will start running with speed of slower one. So I had to tell how many groups will reach the final destination .                                        https://www.geeksforgeeks.org/water-drop-problem/ (similar to this)
2. Maximum number of 1’s in a row in row-wise sorted matrix containing on 0 and 1 in linear complexity. https://www.geeksforgeeks.org/find-the-row-with-maximum-number-1s/ (O(n+m) variation )
3. Write full code to print 360 view(top + bottom) of a given binary tree .

This round was about 45 mins long .I was able to solve all the questions. In the end he asked me if I have any questions for him and then told me to wait outside. HR told me that I’ll have a Round 3 and was called for round 3 in about half an hour. 7 out of 11 were selected for round 3 .

**Round 3: **This was again a F2F Technical Interview / problem solving round / project discussion .

First there was discussion on my projects for around 15 mins in which he asked me about my projects and some questions on android.

Question on android were:

1. what is gradle ?
2. What is DVM(Dalvik Virtual Machine) and how does it work ?

Then I was asked these coding questions :-

1. All combinations(Brute force, O(1) space, Hashing) of pair of values in array with sum equal to a given value. https://www.geeksforgeeks.org/count-pairs-with-given-sum/   and then extended it to find triplets in array with given sum .
2. This question was a different analogy of 0-1 Knapsack .                                           https://www.geeksforgeeks.org/0-1-knapsack-problem-dp-10/

The round was about 40 mins long .I gave answers to all the questions. . In the end he asked me if I have any questions for him and then told me to wait outside. HR told me that I’ll have a Round 4 . 5 out 7 were selected .

**Round 4: **This was a F2F HR round .

The interviewer was very friendly and asked general HR questions . First he asked me to introduce myself, then questions about college, my studies, subjects which we are studying and we had a nice talk . The round was about 20 mins long. Then he told me to wait outside .

3 out 5 were given the the offer and I was one of them .

The thing with these technical interviews is to know the candidates’ thought process behind approaching a problem. They give you hints if you get stuck somewhere, they ask you to optimize the approach if they know this can be optimized further. After discussing the approach you are asked to write code on paper.

American Express Interview Experience | EDA/CFR (INT+FTE) VIT 2020

Round 1:

Platform was mettl. 60 mcqs in 45 mins and 2 codes in 30 mins. Codes were very easy. They shortlisted 35 students for the next round.

Code 1- Mathematics question paper has certain number of questions and each question is assigned some random maximum marks. Mr Myers want to edit the marks assigned to the questions such that all questions in the paper should have distinct maximum marks. The total marks of all the questions should be as low as possible. Mr Myers wants to achieve this by making minimum changes in the original format, assigning the question at least as much marks as it originally had find the minimum total marks that he can set the paper for.
