This is in continuation with our previous blog post, adding some more interview experiences from the batch of 2016-18.

Adhikari Vushesh Babu – Dual Degree ( B. Tech. + M. Tech.) in Information Technology, ABV IIITM Gwalior, 2016

Duration: 40 mins

- HR question about the following scenario- Let’s assume many companies are willing to visit your college this year and you are made the placement representative for your batch. What Steps would you take so that you will get all the credit for your batch placements and not placement season? List some of your initiatives which you think will help you in taking that credit.
- Having completed post graduation in Information Technology from IIIT, why do you want to pursue Career in Business analytics?
- Questions in core engineering part- Merge sort or Quick sort and in what cases would they work better with examples, also explain their worst case complexities. Explain Dijkstra’s algorithm with an example.
- Questions in probability and statistics part-If I were to toss an unbiased coin 10 times, how many heads should I expect? If the coin is biased and the probability of head appearing is 1/3, then how many heads do I expect in 30 trials. Explain Taylor’s series and its uses. Where are complex numbers used in real life?

SUGGESTIONS – Just brush up your knowledge on probability, Statistics and your engineering mathematics. Have a look at sorting and search algorithms. Also be prepared to answer why a career in Analytics.

*Shubhodeep Dey – B.Tech, Chemical Engineering, NITK, Surathkal, 2013; 33 months of experience in Petrochemicals, Reliance Industries Limited*

Duration: 20 mins

I had done a lot of projects during my job so they started with what is the most innovative thing you have done. As soon as I started with my answer, they started asking me random questions on the assembly line (petrochemical industries don’t have anything related to assembly lines). I was able to answer some of them. Then they drew a curve on the sheet and asked me what is the covariance between the data points. I had a good idea about this concept so I could deliver. They moved on to probability and wanted me to visualise a binomial distribution for the number of defectives being produced by a lathe machine given a probability of finding a defective. I could satisfy them by writing down the equations. Some more probability questions followed on coin tosses. My interview ended with a concluding question – what are the major oil producing economies which are not a part of OPEC?

All in all, it went fairly good, I got stuck on few of their questions but they were kind enough to guide me. You don’t have to know everything, what they are looking for is the approach to the problem. Confidence and clarity of thoughts are key factors. The written exam had a heavy contribution in the final selection.

*Parag Bhandarkar – B. Tech. in Electronics Engineering, VJTI Mumbai, 2014; 23 months of experience as a Software engineer, Diebold*

Duration: 20 mins

- Describe your work experience. What are the skill sets learnt during work experience? Domains worked on? Who are the competitors for my company (Diebold)? How will you use Analytics for ATM Industry? What is the reliability in Software domain? What factors affects it? Which affects more – Software / Hardware? and why?
- 2 basic mathematics questions-Based on definite Integrals of some box function, Integration of some trigonometric function

SUGGESTIONS-I think admission committee looked for a balanced profile. It was also written on the website that they will look for Academic, test score and interview performance. As my academic performance was very good, despite “only-good” performance in test and interview, overall weight got balanced.

So I was asked 3 popular political parties of West Bengal, Delhi and Punjab, what are the major issues affecting people in these states, what was the issue going on among Kejriwal, Punjab and Haryana related to the water supply to Delhi.
- Questions related to programming as I had programming background. He wrote few numbers and asked me what will be the best algorithm to bring 6(a number which was in the middle of the series) to the second position. It was a question on sorting. They asked me to write down the algorithm.

SUGGESTIONS – I guess they are judging your willingness and enthusiasm for this program. How much you can think to get to the answer. Sometimes they also look for your thought process instead of the right answer.

What does the SAS output of linear regression model indicate? What’s the difference between causality and correlation?
- 1 basic question related to geometry- if you move 5 km towards North, 5 km towards South-West and so on, finally where would you be as compared to the starting point?
- SUGGESTIONS – They don’t expect the final answer to be correct always, they see the thought process involved in solving a problem. Be very confident about the projects you have mentioned, mainly which are related to analytics.

- What is hypothesis testing? Type-I, II errors? Test statistic? significance level? How do you define risk and decision making?
- Given a signum function, discuss its limits and continuity, differentiability.

There were 3 questions from statistics:

What is CDF? At a given point what will be the pdf? Can you derive standard deviation?

They asked most of the questions from maths after knowing my interest in mathematics. The questions are (not necessarily in order):

1. What is the differentiation of X!?

2. One question from definite integral.

3. Differentiate log X by first derivative method.

4. Integration of log X ( I was also questioned for a particular method to find the solution).

5. Sketch the curve of log X+1 with steps.

Few questions on current affairs: Currencies of different countries . About maps. US elections?

They asked a few HR questions as well – why we should not select you? Why I am not going for a job? My final year project.

*Gunja Agarwal – B. Tech. in Computer Science, Jaypee university, 2015*

Duration: 35 mins

- Tell me about yourself. Do you have other interview calls?
- A puzzle was given to solve – there are 3 bottles and a coin, so the probability of choosing a bottle is 1/3 but you have to get this probability by flipping a coin. What is the method to achieve the desired result?

Answer: flip the coin twice and assign each bottle a unique id i.e TT, HT, TH, HH. But there are only 3 bottles, so create a dummy bottle and assign HH to it. Whenever while flipping a coin HH comes, you need to flip it again till a bottle is chosen. This way we can form an infinite GP series. - Opinion on JNU event
- Questions on Computer science subjects like- what is deadlock and some famous problem which is yet not solved? Name the layers of networking in order? What is a graph and difference between a graph and a tree? I was asked to write the pointer program in C and was also asked to explain it in detail

Feedback: In my case, I think my higher secondary school marks in mathematics and graduation marks help me to grab some brownie points. Also, I was able to crack the puzzle confidently that they asked in the beginning.
