1. Carefully study the types of questions that converted candidates on this PGDBA WordPress page similar to your own profile have been asked previously in PIs. 2. Your motivation for joining this course will be studied very closely by the 3 panelists. Have a very clear opinion on why you want to join this course in particular. 3. Revise Higher Maths topics, specifically Linear Algebra, Basic Statistics and Probability. 4. For Freshers - you may be asked more questions on your grad - level subjects, your internship, any project you did, so be better prepared in that domain. For Experienced folks -  you may be asked more questions related to your workex, and regarding the domain you're from, so you may plan your preparation accordingly. 5. Finally - no amount of preparation will guarantee that you have an answer to everything asked by the panelists. If you don't know the answer, don't fret and tell them so rather than beating around the bush.

1. Tell me something about yourself. 2. What are the qualities of a good manager? 3. What is the difference between a manager and a leader? 4. What are your strengths and your weaknesses? 5. Highlight a marketing strategy you used in your domain to your advantage.

Maths & statistics questions

Q1. What do your parents call you? In how many ways can this name be permuted? Explain this formula intuitively. A: 5! / 2! Q2. What are the types of errors in Hypothesis Testing? A: Type 1 and Type 2 error. Q3. (Gave a problem) What is the type 1 error of this problem? A: Was unable to solve, so told the panelist that i was unable to arrive at an answer, and explained my approach to him. Q4. Let's say you want to estimate the number of Red colored Maruti Altos running in your city. How will you approach this problem? A: * The population of my city is approx. 1.8 Cr. * Let's say there are 5 members per family. Therefore total families = 1.8Cr / 5 = 36L. * Let's say that there is 1 car per 2 families. Therefore total cars = 36L / 2 = 18L. * Maruti Suzuki has a market share of about 50% in Delhi. Therefore total Maruti cars in Delhi = 18L * 50% = 9L * Alto has been one of the best selling cars of Maruti Suzuki. Let's say 10% of all maruti sales have been that of Alto. Therefore total Alto cars in Delhi = 9L * 10% = 90,000 * Since Red is not a common color, let's say only 2% of the Alto cars sold in delhi were of Red color. Therefore total red colored Maruti Alto in my city ~ 1800 cars.

If you have done any projects related to ML /DL better be prepared with what you have done, because it would project a bad image if you couldn't answer from the topics which you claimed that you have worked on or know. I have taken mock interview sessions before attending the main interview which was helpful. I have followed the following YouTube channels: JB Statistics : Statistics 3 Blue 1 Brown : Linear alegebra Machine Learning : Statquest

Work-ex / profile questions

I had an online interview due to Covid. The first question is as expected by me, introducing myself, for which, I have mentioned my academic and work background including the ML related projects, which I have done during my UG, having been prepared to answer any questions related to my ML projects but my first question came from mathematics. The panelist has given me a hypothetical scenario where I have to set up a steel plant abroad. What are the things I have to look for before selecting the place to set up the steel plant. I have mentioned the prominence of abundant water supply for steel plant, Labour laws of that state, availability of cheap labor, transportation system inside the country and export restrictions of the country. The panelist then asked a question on labor laws to which I honestly admitted that I am not much aware of it.

Maths & statistics questions

As I said earlier, my first question is about probability. The question is an algorithm that returns value one if the point satisfies the circle condition of unit radius for x and y. I was asked to compute the probability of getting one, for which I have computed the probability of areas ( area of circle to overall domain area of x and y). I was asked what is Poisson distribution and asked me to show the general form of Poisson distribution. A follow-up question to the same, where they asked me if there is any similarity between Poisson and Binomial distribution, for which, I have answered as the no of trials increases for a binomial distribution it would become a Poisson distribution. Another follow up question to the same is which is the limiting case? Is it the binomial the limiting case of Poisson or the other way round what is a Singular matrix?

I had prepared statistics, and engineering mathematics from a few online articles and YouTube videos. I had created a detailed description of all the projects that I had worked on at my job. Prepared and practiced my introduction and answer to why PGDBA.

Work-ex / profile questions

Introduce yourself - The interviewers asked me to follow a structure - Academics followed by work experience and ending with hobbies.

Maths & statistics questions

1a. I mentioned that I was interested in sports, and the mathematics behind it in my introduction. The interviewer asked me to give my opinion on whether the batting average in cricket is a good measure of the batsman's 'average' run-scoring performance, as it does not take into account the number of innings when the batsman remained not out. - Explained that the term given for the measure can be a bit misleading if considered as an average per inning, as per my understanding, it actually is a measure of how many runs a batsman scores before getting dismissed (between two successive dismissals) 1b. The interviewer asked me to then suggest a better metric for measuring the per inning average score by the batsman. - Suggested the use of quartile scores. 1c. Can we give make a rewarding adjustment to the batsman's score if he remains not out, comparing it with his current average performance? - Each inning is affected by a multitude of factors, rewarding on the basis of just the historical performance may not be the most optimal choice. If a reward score is given, should also penalize the batsman for getting out before his average score. 2. Give an example of numbers that have the same mean and standard deviation. - (0, 0, 0, ...) will have the standard deviation 0 and mean 0. The interviewer then asked for a non-trivial solution and asked whether (2, 0) will satisfy the given condition. 3. Describe hypothesis testing, what is significance level.

Coding / ML questions

1. Describe your work experience - I worked as a data analyst in the audit/assurance service line. Explained that audit requires considering each data point, and which was previously being done on a sample basis. 2. What is the typical audit data size, in terms of the number of rows and columns. 3. What tools did you use - I worked with Tableau, Python, and Alteryx. 4. What Statistical tools did you use - Talked about a few projects I had worked on, as the statistical tools varied from project to project. example: One of my projects required applying Benford's Law, explained what it is.

GK & current affairs questions

As I was from Mumbai, the interviewer asked me to explain the reasons behind farmer suicides in Maharashtra.

Logical reasoning / puzzles

1. What is Assurance/Audit - Talked about the etymology of the word audit, that it meant 'to listen'. Traditionally audit reports were given orally to an audience. 2a. I had mentioned reading as a hobby. The interviewers asked me about the last book that I had read, and what genres I was interested in. - I liked reading Fantasy, briefly described a few of my favorite fantasy books. 2b. I had also mentioned Philosophy as a genre I was interested in, the interviewer asked me how that interest was developed and what book was I currently reading. - Cognitive bias was a topic I was interested in, and how that affected rational thinking. The philosophers devoted their lives thinking and reading about their perspectives may help to improve rational thinking.

Incidently, I was not asked for Introduction. I was however asked why I was interested in the Program, which I related to my interest in Applications of Business Analytics to the fields I was interested in, (Cartography, BFSI & Healthcare). besides my interest in Statistics and Inference. I was not asked any questions related to my Core Undergraduate Courses.

Maths & statistics questions

Statistics: Properties of PDF, f(x) for Geometric Distribution, Memoryless Property, Moment Generating Functions (and by Extension Characterstic Functions), Quasi-Random Variables [Had No Clue Regarding this during the Interview], Jacobi Method for Calculating the Probability Distributions for Functions of Random Variables, Unbiased Estimators (E(theta cap) = theta), Cramer Rao Lower Bound for Variance) Linear Algebra: Idea of Linear Transformations, Linearity Property, Matrix as a Linear Transformation, Projection as a Linear Transformation from RXRXR to RXR Calculus (Class XII): Limit for Sin(x)/x as x tends to Infinitly, Mathematical Definition of Continuity Linear Programming Problems (Class XII): Basic Definitions - Objective Function, Constraints, Feasible Regions, Feasible Solutions, Basic Variables, Bounded and Unbounded Polygons, Conditions for Unbounded Solutions [No Maximum/ Minimum] and No Solutions [Constraints with Conflicting Requirements] for Linear Programming Problems, Introduction to Simplex Method

Coding / ML questions

Most of my Interview was centric to Mathematics related Courses (Graduate Level Statistics, Linear Algebra, Class XII Level Calculus (mainly Limits), Class XII Level Linear Programming Problems). I was however prepared for Machine Learning (Andrew Ng's Course in Machine Learning is a good starting point), SQL, Data Structures, Algorithms and Graph Theory (due to my Work Experience as a Software Engineer)

GK & current affairs questions

Since I was previously a Student and Intern in Taiwan (2017-18) and China (2018) and had attended a Volunteer Work related Conference in Bangladesh recently (2019), most of my General Awareness Questions were centric to History and Geography (but not Politics) of these Countries. China-Centric: Local Language spoken in Guangdong and Guangxi, Administrative Divisions of China (Provinces, Autonomous Regions, Special Administrative Regions, Directly Administered Municipalities), Once-China Policy, Political Parties of China and Taiwan (CCP, KMT, DPP) Bangladesh-Centric: Year of Independence of Bangladesh (1971), Trains to Bangaldesh (Bandhan & Maitree Express), the 2015 Land Boundary Agreement (& the Concept of Enclaves & Exclaves), Political Parties (BAL, BNP) Others: Capital of Pakistan prior to Independence (Karachi)

Logical reasoning / puzzles

Be sure to have a post interview conversation with the panelists in the form of a question (either Technical/ Non-Technical) or in the form of a remark, to close the interview on a good note. [For me, it was Discussion of the Attitude on Indian Students towards Programs in Business Analytics and Narration of a few lines of Amar Sonar Bangla by Rabindranath Tagore to depict my interest in Bengali Language and Culture.]

Use any standard JEE textbook for preparing quant. I used Cengage. For Cengage, go through the theory part completely, try to attempt the solved question given in between along with the exercises. If you are comfortable with these questions then you can ignore the exercises at the end of each chapter. This will be more than enough to secure 100% in quant. 1 month prior the exam, join any telegram group in which people posts questions daily. This will help you immensely. For LR-DI-Verbal, use any standard CAT material. The level of PGDBA will be lower than it. In the last month try to practice at least 1 passage,  1 problem set of LR and DI each everyday. Strategy - Focus on obtaining 35 questions of quant, LR, DI correct (easily attainable). If you can secure marks around 130/150, there will be less dependency on interview marks (very random) and you will have great chances.

VARC: The level was somewhat similar to CAT and other MBA entrance exams. One can practice from previous year cat materials or something related to that and it will be enough. There would be some para jumbles and other verbal type questions too. Plus there are no TITA type questions. DILR: It's the easiest section in PGDBA. Almost everyone scores full here. You can check previous year PGDBA papers and you will get to know about it. If you still feel that you need practice then you can practice the very basic questions from cat sample papers. QUANT: Here one has to put a little more effort. It includes topics such as calculus, limits, continuity, conic section etc. One can say it contains almost all topics of 11th and 12th. For this one has to revise NCERT books of both 11th and 12th. Also, if one has time then he/she can practice questions from RD Sharma Objective Mathematics . This will be enough.

Practise speaking impromptu in front of the mirror. Improve your articulation. Instantaneous conversion of our thoughts into the most meaningful words is a skill that comes only with experience. Do not mention anything in your form which you cannot defend. Be honest with the panel and do not even think for a second that you can fool them by over-selling yourself.

Work-ex / profile questions

No question asked on my general profile

Maths & statistics questions

The last panelist (I presume that he was from ISI) asked which topic of statistics was I most comfortable with. I replied in all honesty that I have zero background in statistics, not even at the UG level. Then I told him that I felt strong enough in Calculus and computational methods as far as mathematics is concerned. So, I was tested on the fundamentals of calculus. I was asked to definite continuity, distinguish it from differentiability and then give examples of functions that are continuous but not-differentiable and vice-versa. I was tested on differentiability of some functions posed by the panelist. In the end, he asked me to compute the integral of the greatest integer function from 1 to 10 without using any paper/pen/calculator. All questions were framed as a natural corollary to one another. There was a hint dropped when I was stuck in the middle of a question. There was however not much time given to think before responding.

Coding / ML questions

No Analytics/ML/DS question asked

GK & current affairs questions

One panelist asked me questions entirely on global economics. I was asked about Brexit, its impact on India, WTO, special initiatives to promote manufacturing in India by the Govt., economic soundness of the recent decision to raise import duty on a lot of technical goods. There were a lot of questions one after another around the common area spanned by these topics.

Logical reasoning / puzzles

My interview started with the first panelist straight away asking me why does a ship not sink even though it is so large. How does a yacht capsize? What are the types and directions of friction acting on 2 wheels of a bicycle? and so on. All the questions were from concepts involving class 12th level physics. I was found wanting in conceptual clarity in these topics.

Maths & statistics questions

The first panalist  asked me to solve a problem I tried and I couldn't. I politely told the interviewer that I was not getting it. The panalist tried encouraging me to solve it I tried for a while but couldn't so I told him that I didn't want waste the time dwelling on that single problem. He said fine my work is done and passed on to the next panalist. I was expecting another problem from him but his response sent a couple of chills down my spine. The next panelist asked me what did I know about statistics as I was from mechanical engineering background. I told him that we use statistical quality control in mechanical engineering and I told him that I have gone through a book called statistics for engineers by Anthony hater. He tested on that by giving different scenarios and asking what would be the probability distribution it would follow. I remember that the panelist had asked questions about distributions that were mentioned as optional/additional study in the book. I was so happy that I didn't skip those while studying. He then asked about Memoryless property of distributions and then passed on to the third panalist.
