Round difficulty - Easy

It was in the day time. I was asked the programming language of my choice. It was mostly focused on programming fundamentals. I was asked 2 questions based on Data Structures and Algorithms.

  • Q1. How can you detect a loop in a linked list?
  • Ans. 

    A loop in a linked list can be detected using Floyd's Cycle Detection Algorithm.

    • Use two pointers - slow and fast, where slow moves one step at a time and fast moves two steps at a time.

    • If there is a loop, the two pointers will eventually meet at some point within the loop.

    • To detect the start of the loop, reset one pointer to the head and move both pointers one step at a time until they meet again.

Interview Preparation Tips

Round: Resume Shortlist
Experience: My resume had a couple of projects and a paper publication added to it, which was a part of my second year intern at TCS Innovation Labs.

Tips: I believe that the resume shortlist to appear for the test is just a formality and not a big deal to get through. Most of the students are allowed to appear for the test which is where, the main shortlisting occurs.
Although, the company does cut off people from certain departments. For example, none of the Agriculture and food engineering students were shortlisted for appearing for the test.
Also, from what I have heard, the company runs resumes through a program to take out the shortlist. Hence, certain key words such as "Scholar" or "Conference" may get you a good chance to get through the shortlisting.

Round: Test
Experience: The test is mainly quant based and how fast you can think and rationalize. They expect excellent speed; they ask you 20 questions to be answered in 30 minutes.
Tips: Normally, if a student is asked to appear for this right after his JEE examination, he would be able to get through it easily. But since our analytical thinking goes way down once we actually get in, it has to be worked upon again. I'd suggest you to solve all the quant questions of any CAT preparatory book for the American Express test. The test questions are quite similar to those that the CAT students prepare for.

Round: Technical Interview
Experience: In general, the American Express interviews are considered to be pretty peaceful compared to the interviews of other companies. I was just asked about my work at TCS Innovation Labs and the paper I would be publishing based on that work and the courses I have done in Data Analytics and what all do I know in it. They do not test the knowledge you say you possess.
Tips: While I was preparing for my interview, I was told to read about Amex and its products. Secondly, and most importantly, I was aksed to read a lot about credit card frauds and suggest ways of preventing that. Even during my time, a lot of people were asked about this and judged severely on that. This is a must must if you would be appearing for its interview.

Also, you would do well if you are able to connect with the interviewer. For instance, if both of you have been a part of the same inter IIT or have the same tastes, etc.

Also, the interviews are that peaceful that you are able to direct the interview in your favour. There are certain parts of your CV that you can easily talk about and certain parts that you would want to avoid. If you are able to think on your feet, it is easy to re direct the interview in your favour and the things that you would like to talk about; in my case, it was my work at TCS.

Round: Puzzle Interview
Experience: The main decision whether you have to be taken in or not is decided in your first round of interview after which, the puzzle interview is just a formality and to find out whether you are able to think on your feet or not. Not a big deal, pretty easy.
Tips: Nothing to be worried about, the puzzles asked are pretty easy and most probably, you would have already heard them if you have a nag of solving puzzles.

General Tips: Do not worry or stress yourself much. The interview is pretty easy if you have an edge in the skills that the company wants. I had started studying Data Analytics in my second year summer vacations, just 1 hour a day for hardly about a month. Which gave me enough of an edge. The main hurdle lies in getting through the test round where about 300 people are simply cut off.
Skill Tips: You should be able to code efficiently. Knowledge in Python and SQL is a big plus.
Also, I had done a course on Coursera called "Machine Learning" of Stanford University. Today, the company does not expect a lot of knowledge in Data Analytics from students which is why this course gave me the edge I needed to get through the interview. It's a pretty easy course and not very demanding. I would recommend this if you want to find out even whether you'd be interested in Data Analytics or not.
I was asked about the things I know and whether I have ever implemented them.

College Name: IIT Kharagpur
Motivation: American Express is known to have a good working culture and is currently the third best company to work for in India. The internship stipend is largest compared to any other company in India along with accommodation and travel. The company has a well structured internship program and also has good challenging work to offer.
Funny Moments: After the test, I was not shortlisted for the interview round.. Which broke my heart.
Just after the presentation, I walked up to the person presenting and handed him a hard copy of my resume asking him to at least give me a shot at the interview if they think my profile is good enough.
I believe that this was a turning point of this entire experience. I believe, at that moment itself, I gained their favour to take me in. Which is probably why my interview was peaceful, which is probably why I could get through even though my interview was the last among a bunch of 25 students..

Interview Preparation Tips

Round: Interview
Experience: The interviewer also said: "It seems like you are more interested in finance and BCG is only the second option. We don’t like being the second option." All these questions required some delicate handling.

Round: Interview
Experience: This was a sort of stress interview because the interviewer seemed disinterested and dissatisfied with everything i said and kept on demanding for more while impressing that whatever I am coming up with was really of no significance.
Tips: What worked in my favor was I dint get flustered by his attitude, kept smiling and working at the problem objectively. When I would come to the end of one line of thinking and would have no more answers to his “What next” I would frankly tell him that and ask him in return for more suggestions. It resulted in him complimenting my way of thinking at the end and saying that I was one of the best and most practical candidates that he had interviewed that day.

Round: Interview
Experience: 1. Both the above questions were the part of one interview.
2. The interviewer didn't want me to solve the case fully in either instance. He just wanted to see my structure and evaluate my thinking process.

Round: Interview
Experience: Almost all my interviews went well with BCG except the last VC one, because by then I was complete drained out and could hardly think. I also did some minor silly mistakes in a couple of the smaller cases while dealing with numbers, but otherwise everyone seemed to appreciate my structuring of the cases. Some of the interviewers also delved into the HR side frequently.

Round: Technical Interview
Experience: Technical on paper test questions:(dis was only for 12 among d 26 shortlisted ppl after apti...others directly had interviews)
5 wer selected in this test who wer nw sent for interviews
TECHNICAL INTERVIEW: (pls list the questions asked in all the rounds)
26 shortlisted after apti (14 directly for interviews & 12 had one more technical on paper test...mentioned above)
der wer min 2 technical rounds for each of them...max were 5

- You are given course dependencies
A->B,C
B->D
C->A
D->nothing
The above dependencies mean...if you want to take course A...you should take courses B and C first....To take B,Course D must be taken first....D is an independent course and can be taken without any prior requirements.
Now you are told these dependencies.Come up with an appropriate data structure to represent these dependencies.Then write a code that finds out all the courses that the student can take up...in this case the student can first take course D because its independent.Now that course D has been taken he can next take up B as it depends on B alone...But the courses A and C can never be taken because they depend on each other...So here all the courses that can be taken are B and D.
After i wrote the code....he asked for all possible test cases
-Given an array of length N....It can be filled with nos. only from 1 to N....find which nos are repeated in the array
-Given pointers to two nodes in a binary tree....find their least common ancestor...each node has pointer to only the parent node...not the left and right child..
-In a binary tree(Not necessarily a BST)...suppose the weight of any node is defined as the product of the key value of the node and the level of the node(Root at level 1)...find the node with maximum weight in the binary tree
-A sorted array of size n is right circularly rotated k times and this rotated array is given to you as input...Find out the value of k in log n time .
-There are some processes running at time T....and there are processes running at time T+30.
You have to find out
1)Which processes died at time T+30,which were alive at time T
2)Which are the new processes at time T+30,which were not there at time T
3)Which are the processes that were there at time T and are still running at time T+30
What data structure will you use to represent the process lists and write code to find out the answers to the 3 questions above
-Given a binary search tree...and a target sum...starting at the root...which all paths add up to the target sum?...if there are multiple paths....return the path with least no. of nodes.
