Round 1

Test

Test Sections
  • Section 1: Written
Interview Experience
The written test was subjective type and had questions mainly on C/C++, UNIX, Algorithms and Data Structures, Probability. The focus was on Algorithms and Data Structures, and in many of the questions you were supposed to code the algorithm you propose.
Round 2

Interview

Interview Experience
I got shortlisted for the interviews and had 3 rounds. All the interviews were of about 1 hour duration. They mainly asked questions on algorithms and puzzles. Sometimes after I gave them the algorithm they asked me to code it. I felt after the process that I could have made it had I revised the algorithm courses thoroughly.
Interview Tips
Thoroughly revise all the data structures and algorithms courses you have done. Get hold of a book like Cormen and solve the questions given at the end of each chapter. Also code the algorithms to get some practice.

    General Tips
    After spending three or four years enjoying the IITK adventure, one suddenly feels a jolt when he/she arrives in the final year. You find yourself wondering at times, asking yourself the pertinent question, what next? And seriously, the best way to start preparing for placements, GRE, CAT or any other exam for that matter is answering this question honestly. Take a few minutes of your precious time and think what you want to do with your life? Where does your heart truly lie? I know it’s not that easy to decide on this but at least give this a good thought and prioritize your options. Make a list of them on paper if that helps. Once you are done with this, the real planning starts. Take each option one by one and do a truthful analysis of yourself from the perspective of that option. For e.g., say you have CAT as your first priority, and then analyze your strengths and weaknesses from CAT’s perspective. What all areas you need to improve on? How much time and effort would it take? How much time you have got left? By doing this exercise you will really get to know the work that needs to be done and will help you plan for the remaining time.<br />
    <br />
    <br />
    Resume:<br />
    I am sure you would have heard it umpteen times but still I will repeat it to stress the point, take resume making seriously! A good resume would drive your interview in the direction you want it to go, a bad resume on the other hand might end the chances of you even getting interviewed! Start by trying to remember each and every achievement of your life and write it down. Spend a few days on this part till you are sure you have got almost everything. Now write it down properly in formal language in the form of a master resume. This would serve<br />
    as a repository of information for all your subsequent resumes. And on top of that, having a fresh memory of your achievements would help you in answering the questions in interviews (especially HR questions). Ideally you should have a separate resume for every company you sit for. The way to do this is make sector specific resumes and edit them accordingly for the different companies of that sector. For example, make a single resume for all the core CSE companies and then you can probably change the list of projects (or their order of appearance) targeting individual companies.<br />
    <br />
    PPTs:<br />
    If you are serious about getting job in a company, you cannot afford to miss its pre placement talk. PPT is not only an opportunity to know about the company, but it also gives you the chance to know what the company is looking for. This will give you the basic idea around which you should structure your resume and preparation for that company.<br />
    Preparation:<br />
    Core Computer Science Companies: All the core CS companies first take a written test which contains questions on C/C++, may have JAVA, UNIX, Algorithms, Data Structures, basics of Operating Systems and Compilers, some questions on basic networking in case the company works in that field. Almost all the companies have a couple of questions in which you are required to write code on paper. Some companies also have a few questions on aptitude, simple maths or data interpretations. You can find the company specific details in the placement feedback guide. This is the major<br />
    shortlisting step for core companies, so you cannot take it lightly. You can start preparing by revising the relevant courses you did (like Data Structures, Algorithms, Operating Systems, and Compilers). Practice a few questions available in the various placement preparation guides on LAN. Most importantly, practice writing code on paper. This is something we are not used to and requires some practice. This not only will do you good in the written test, but also help you in the interviews.<br />
    Non Core Companies (Finance, Consulting, and Analytics):<br />
    The written tests of most of these companies are quite similar to CAT. So if you are not preparing for CAT, get hold of some CAT preparation material for practice. These tests are more speed based than knowledge, so practice is absolutely essential. Revising some basic mathematics (like probability, progressions etc.) would also do you good. Apart from that, you need to have some basic knowledge and understanding of the field the company works in. For example, if you are appearing for a finance company, learn the basic concepts and common terminologies of finance. The least it would do is show that you are sincerely interested in the field the company works in.

    Test

    Duration
    45 min Minutes
    Test Sections
    • Section 1: Given a huge file of words, write a program to print all distinct words in it, in ascending order (huge means wont fully fit into memory).
    • Section 2: Given 2 strings, return the pointer to the first character from the end in string 1 that does not appear in string 2 in better then O(mn) (means O(mn) is not efficient enough).
    • Section 3: There are 2 arrays A[] and B[] where B[i] is the frequency A[i] in the array A[]. Given the array A[] and the fact that all elements of B[] except 1 are divisible by 15, find the value in A[] whose frequency count isn't divisible by 15 (solution involves finding the sums of each column of bits).
    • Section 4: What does the keyword static mean in various contexts in C? What is the difference between char[] and char*?
    • Section 5: Write a class such that only one object of that class can be created. (Google for ‘Singleton’ and ‘design pattern’).
    • Section 6: Given n points (xi, yi) find m and c for the best straight line approximately expected = mx + c such that _(y ? yexpected)2 is minimum. When minimum what is the value of _(y ? yexpected)? (only 1 guy attempted this question and got it correct, mostly because this was the last question and there wasn't time)
    Round 2

    Interview

    Interview Questions
    • Question 1: Started with ’About you’
    • Question 2: Went through written test, asked me to attempt all questions I didn’t attempt
    • Question 3: Went through Resume, talked about internship projects
    • Question 4: Asked a bit about my finance project, asked a few questions like ’Which exchange would you find commodity futures traded on’. I knew some of the answers, didn’t know others - I guess I was asked these questions only because I said I did a finance project.
    • Question 5: Would you prefer to develop mathematical models or to develop the trading infrastructure?
    Round 3

    Interview

    Interview Questions
    • Question 1: Started with ’About you’

    Round 4

    Interview

    Interview Experience
    There are 25 horses, and you can have races where 5 horses can race at a time. Find 3 fastest horses in minimum number of races (7 races).
    – Given a bar, if you cut it at 2 points, what is the probability that you can form a triangle?
    – Given k sorted arrays of size n, merge them into a sorted array in O(nk log (k)) time (use minheap to extract the minimum of k elements).
    – There a lot of coins placed in a line some heads, some tails. You know total coins, number of heads, are blindfolded, can't see or feel a head or tail. Divide into two piles such that both have equal number of heads.
    Round 5

    Interview

    Interview Questions
    • Question 1: There were 7 guests at a party + a host. 1st guest shook hands with 1 guy, 2nd guest with 2 guys .... kth guest with k guys. How many people did the host shake hands with? k was either 6 or 7, probably 7 – I don’t remember exactly.
    • Question 2: The Red-Blue Hat Prisoners puzzle: if prisoner guesses colour of his hat he lives else dies. Idea is to save as many prisoners as possible. Actual solution saves n-1 prisoners but I hadn’t heard this puzzle before so somehow got a solution that saved n - log(n) prisoners. He was happy with this answer since he hadn’t heard this solution before.
    • Question 3: Given a round table and a lot of round disks, develop a strategy where you win always given that you and opponent have to alternately place disks and the last guy to place a disk wins.
    • Question 4: Puzzle where you have a square spiral path. In one move you can move forward as many times as you want if you go straight or if you are at a corner, move inward to the next corner. The person to reach the centre of the spiral wins. You have to develop a strategy to win.
    • Question 5: He asked me the 8 ball weighing question but I told him I had heard it.
    • Question 6: Questions you have? I asked about his plans for the next few years.

      Other Interview

      Interview Experience
      There were 4 rounds to my interview.

      Round 1(Madhuresh Agrawal):
      He asked a lot of puzzles. Apart from knowing how to approach a problem, you should also know the mathematical reasoning for their correctness.

      Round 2 (Abhishek Gaurav):
      He asked some more puzzles and some probability (expectation) questions. Then, he modified one question asked in the written test and asked me write code for it on paper.

      Round 3 (Anand Sinha):
      He asked questions related to graphs. Several times, he tried to trick me by asking questions like "How would you tell whether a graph has a node with n degree?" whereas no node can have degree = n.

      Round 4 (Anand Sinha):
      He asked me write 2 programs: 1. Given k and DFS traversal string for a k-ary tree, construct the tree. The String contains P (if a parent) and L (if a leaf). E.g. - k=3, str="PPLLLLL" 2. All the strings are arranged in the following order: A,B,..,Z,AA,...AZ,BA,...,BZ,... That is, first according to length and then according to alphabet (assume there are k alphabets instead of 26). Now, given a string, finds its position in the mentioned sequence.
      Interview Tips
      First of all, prepare all the questions asked in the test before going for the interviews.

        General Tips
        Well, for my story, I'll start right from the 3rd year. For me that was the time when I started thinking about what to do after graduation. Believe me, this is the toughest and the most important question that needs to be answered. For most people, they have a clear idea about what they want to do in future. But, if you are not one of those lucky ones, you should really spend some time thinking about your future. There are of course, some people who are confused and try their luck at everything. Take my advice, don't be that person. You would<br />
        end up nowhere that way. Now, the question remains, how to decide which way to go. Well, being an IITian, we all are good at problem solving. I tried something similar here. Try to know more about the various options available to you. To name a few: MBA, Civil Services, PhD, Job (core, IT, Consulting, Analytics, Finance, FMCG), NGO, Journalism etc. Although I've mentioned MBA and PhD in the list above, I didn't consider them as options. Those are merely the means for achieving a higher goal. So, I looked at the bigger picture, what I really wanted to do in my life. I attended some of the PPTs (don't worry 3rd yr. students are allowed to attend PPTs). And to clarify my doubts about a corporate life, I also chose a company intern. When I had enough information about my options, I matched them with my likes/dislikes. Now, you shouldn't chase big money unless it is the only thing that you<br />
        want. Even simple likings like partying, travelling or free time in evening do matter. If your job doesn't give you all that you won't be happy with your life. And if you are not happy with your job, you won't do well there as well. I didn't apply for McKinsey, ITC or Deutsche bank as that is not the kind of life I want to live. So, choose what you want to be (you may not be able to pinpoint it but at least narrow down your options). Then, find out what you<br />
        need to get there. For example, if you want to be a researcher or a professor, you would need<br />
        at least a PhD.<br />
        <br />
        Then, came the task of deciding which companies to sit for. Once you know your goal, you can decide what type of companies you want to apply for. Attending the PPTs and the notes I made of them came in handy for this purpose. Don't just look at what company does; find out exactly what your role would be. Then comes the threshold. Shortlist the companies in which you would actually be interested in going. Don't apply in a company which you won't join if you get the job.

          General Tips
          Pre-Placement Preparation1) Selecting sectors or companiesSelect your group of target companies and sectors. You should realize what your interests are and what kind of job would suit you, and according to that you should prepare a list of companies that you are going to focus on primarily. This list should not be too narrow that you have too few companies to target and not too broad that you end up sitting for every company visiting the campus.2) Attending PPTsThe PPTs and the workshops organized by the companies form a key input in the decision process of choosing the companies. Be attentive during the PPTs and note key points mentioned – like the profile, compensation structure and the contacts of the people (especially alumni) in the company. This helps a lot during the preparation for the particular company.3) ResumeThe best way to start the preparation for the interview process is to start by making a list of all things that you have done in your life. This list should contain every small and big thing that you have done. Once the above list is made, make a master resume out of the list by retaining all the important things and putting them into formal language. The smaller works can be kept for narrating during interviews. If your master resume is properly made then preparing company tailored resume becomes very easy. After the master resume is done, it is time to make sector/company specific resumes. Every sector must have different resumes and, if possible, also make the resume specific to every company. Take feedback from your friends and seniors and make necessary adjustments.4) Communication skillsYou can make a GD group and conduct regular GDs to help you prepare for the GDs. In fact, also ask your friends to conduct mock interviews and record these interviews. You will actually come to know what to do and how you react during the interviews.5) Written TestsIf you are targeting companies that take CAT-like aptitude tests, then prepare for them by solving some CAT papers. These tests just check practice and someone who has been preparing will definitely have an edge over a person who is not in touch.6) HR InterviewsMake a list of the commonly asked HR questions and then prepare answers for them. Do not learn the answers by heart but make sure you know the important points that you want to mention for each question.7) Case InterviewsThe best way to prepare for a case interview is to form groups and solve case studies interactively as you would do in an interview.8) CSE PreparationFor the CSE companies, I brushed up basic data structures and algorithms as well as C/C++ and Java. Other than that, I also glanced through Operating Systems, Compilers, Networks and databases. Make sure that you understand the basic concepts behind these things as well as particular details of popular implementations of each of these systems.

            Do read OS and DBMS, as you can miss your dream company just<br />
            because objective questions on these topics went wrong. In my case the company was Google.Make sure you have at least 1 wing mate with you during the entire process.Carry a lot of fluids and some snacks as the day will be demanding.Do not sit for more than 3 companies on the same day.Do not panic. Enjoy the day and in the end you will be rewarded.Give your best, speak with confidence.
            Motivation for applying
            I had two offers at the end of slot 1, day 1- one from Tower research and the other from Oracle US. Tower had a much better reputation and had a stronger growth curve. base pay was higher.

            Interview Experience
            I looked at resumes of previously successful candidates with profiles similar to mine. After reaching a level I thought fit, I sent it for review to several friends, mostly those who'd already appeared for placements the previous years. In particular, I sent it to people in companies where I was applying. Feedback from them dramatically changed my resume.
            Interview Tips
            The PPTs helped me eliminate (rather than choose) companies I'd want to apply for. I usually found people in the companies I thought I'd like to apply to or people in similar positions in other companies.

              Next, he went over the written test that we had taken the previous day. He asked me whether I had tried any of the questions after the test. I was honest and told him that I did not expect to get shortlisted for Tower, since I had not done the C/C++ intensive Computer Science questions in the test and had done only the language-neutral / algorithm-based questions, and because I had two other interviews today, I had spent my time preparing for those. He was happy with that answer and asked me to try some questions in the interview.

              I came up with an answer to one question, to which he gave me two hints to improve. I managed to use them in making the algorithm more efficient. Then he asked me some reasonably easy puzzles which I answered without difficulty. Lastly, he asked me to solve another question using an algorithm and a similar sequence of hint-giving and algorithm-improving followed.

              By the end of this interview, I was very confident and totally tension-free. This was because I had performed my very best in the Tower interview, and I couldn’t imagine how I could have done better, given my background (limited CS) and preparation. In that sense, this interview made me lose all my interview-anxiety, and was crucial to my placement day.
