- Ans.
Answering a question about estimating quant score and overall score in finance.
I estimate my quant score to be X based on my preparation and practice.
Adding my quant score to the avg finance score may or may not result in the highest overall score, as it depends on the scores of other candidates.
However, I am confident in my abilities and believe that I can perform well in both areas.
I am open to discussing my preparat...

Interview Preparation Tips
Experience: 28 questions, 18 quantative + 10 financial awareness, negative marking. I took one pass through the Quant section, leaving about 5 questions, went on to the financial section, realized I wasn't going to score that well there so went back to Quant eventually attempting all 18, having to guess 1 answer since I ran out of time. I attempted probably 2-3 in financial. The test matters a lot to get shortlisted - some CSE students didn’t get shortlisted apparently because of a low test score. I would suggest that focus should be primarily on the quant section rather than the finance section - a friend in CSE who said he did well in the finance section didn’t get shortlisted.
Quant
1. Find next in sequence : 10,1,.......7,7...11,5 - don't remember the rest of the sequence but it looked random
initially it but if you take the difference between alternate terms an obvious pattern emerges .
2. Probability of two people telling the truth = 0.4,0.6 - what is the chance that they are inconsistent in what they say ?
3. A 3 digit number is a square less than 500, the reverse of the number is also a square. on repeating last digit still a square. What is the difference between the initial square, its reverse.
4. In a 1000m race if x gives y a head start of 40 meter, x wins by 10m. how much will x win by if y gives x a head start of 40m
5. With 16 matches, how many distinct triangles can you make?
6. You row at 7kmph in a calm lake. fisherman drops something 14 km upstream and the river current is 3kmph, how long will it take to reach you (14/7 = 2hrs ).
7. The sum of the multiples of 7 between 200 and 400 is what (trick was instead of calculating, to observe that the answer is odd and of the 5 options, only one was odd)?
8. Sum of consecutive page numbers in a book starting from 1 to n is 1000 - one page was repeated. which page was it? (idea was to subtract each choice from 1000 and see if it was n _ (n + 1)/2)
9. Last digit of 508508
10. 6 men + 4 women. Make a committee of 3 from them - Guy X wont be with Guy Y. Guy Y will be only with Woman Z in committee. How many ways of making the committee?
11. Run in circle of radius r. 1st 30 seconds at r meters/min, then next 1 min at r/2 m per min next 2 min at r/4 and so on. ratio of times taken in round n, previous round
12. |(x ? 11)/2| < 3 what is the range of x?
13. number of integer solutions to 3x + 6y = 13 (take 3 common on LHS and the answer is clear).
14. 5 students give an objective exam (+1 for correct, 0 for wrong) with 5 questions each with 5 choices. Their answers were given in a 5x5 matrix. Given they all got different marks, who got the lowest.
15. A,B,C,D stand in a line in increasing order of height. Given that X was shorter than Y but didnt stand first, and (a few more conditions) , who stood last? (X and Y had been specified as one of A, B, C, D - I don’t remember exactly since I gave the test 10 days back).
Financial
1. Rupee-dollar exchange rate (options were ranges of 1 rupee answer ws 39-40)
2. value of some index (some non-Indian East Asian country’s stock market - I forgot the name)
3. Effect of interest rate cuts on a bond coupon
4. Simple question on call option - which of following is not true about it
5. 1st Indian IT company to be listed on Nasdaq
6. Given a pie chart where it showed that for capital, a company relied 80% on equity and a small fraction on debts, what investment strategy is the company using? Conservative/Aggressive?
Duration: 40 min minutes
Round: HR Interview
Experience: I was the last person DB interviewed that day. Towards the end, the interviewer said “I am sure you are going to join Tower Research and not DB”. They also seemed to have decided before I came in to the interview that I would get an offer with some other company and would not choose DB - kept attacking the answers I gave to ‘Why not Microsoft/Tower’. In hindsight maybe I shouldn't have listed all the 4 tech companies I had interned with.

Interview Preparation Tips
Experience: For CSE and EE students , CPI was not at all seem to be a criteria for shortlisting and almost all who have a decent profile got shortlisted for the test. However, for other department students they shortlisted above 9 CPI students.
Round: Test
Experience: It was a 2 hour test. It consisted of 3 sections-Quant , Machine Learning and Computer Science . Each section had 10 questions and 45 minutes were allotted for each section.
Being from non-CSE background I attempted only 2 sections ie. Quant and Machine Learning. Machine Learning section was fairly easy this time and almost all questions were standard. If someone has done an introductory course on Machine Learning and basic stats , this section was a cake walk for him. However , attempting quant section required some preparation of solving probability puzzles (computing expectations etc.) ,basic linear algebra and geometry base questions.
Duration: 2 hours
Round: Technical Interview
Experience: I had 2 rounds of interview. Both were technical ones.
In the first interview , they asked some probability puzzles (from 50 challenging problems in probability book) . Since I had completed that book before , I was able to solve them . Then they asked 1-2 algorithm based questions like formulate an efficient algorithm for solving a particular problem. I was not able to solve them completely but tried to give them the overview of y approach. The interviewer didn't seem to be satisfied though. It lasted for around 20-25 minutes.He told me to wait outside . To my surprise, I was called for the 2nd round.
The second went better than the first round. They again asked questions on computing probability , expectations , constructing a Markov Chain for a a given problem etc. Since I had done 1 course in Fiance also , he asked me questions from it also which were quite easy. Then he began asking algorithms and asked me to explain a sorting algorithm and I chose Quick Sort. While explaining it , I got struck at one point but the interviewer was helping me by giving hints and I was able to explain it fully. The second round was quite exhaustive as it went on for around 45-60 minutes.

- Q3. Dice rolled several times until sum of outcomes till now comes greater than equal to hundred. What is most likely number to occur as final sum?
- Ans.
The most likely number to occur as the final sum is 100.
The sum of the outcomes of the dice rolls will keep increasing until it reaches or exceeds 100.
Since the dice have equal probabilities for each outcome, the sum will have a higher chance of reaching 100.
The probability of rolling a sum greater than 100 decreases as the sum gets larger.
- Q4. Cutting three random points on the circle of radius 1 centered at (0,0) . What is probability that point (1,0) lies in longest cut

Finding probability of point (1,0) lying in longest cut of three random points on circle of radius 1 centered at (0,0)
The longest cut will be the one that spans the smallest angle between two of the three points
The probability can be found by calculating the area of the region where the longest cut includes point (1,0)
This can be done by finding the angle between (1,0) and the two other points and using trigonometry to...

Experience: Written test (Cut off: 7): The test consisted of 2 sectionsPart A (60 min): MCQ's with negatives on general aptitude, permutation & combination (P&C) and Probability.Part B (40 min): This was a subjective section. One or two problems on probability/P&C and few problems on data structures and algorithms (we were asked to write code).
Duration: 60+40 minutes
Round: Other Interview
Experience: 22 candidates were selected for interview which consisted of 2 or 3 rounds. First round: They asked me to explain my summer project. In the Second round, a few problems on P&C/Probability and couple of questions on DSA. Final round: An open problem. For example: estimate the population of Mangalore.
General Tips: If you don't know an answer, tell the interviewer the same. Lying would do more harm than good because they definitely know more than us and will find out very easily. It was Challenging and a great learning experience They test your fundamentals and don't ask too many difficult questions.
Skill Tips: If they ask you to explain what you did in your summer internship, explain it in as simple a language as possible so that even a person with no background in the subject will be able to understand it. Don't use complicated terms because they are looking for people who can express themselves well. Prepare for aptitude sincerely. You might neglect it thinking "It's just apti, what can they ask?". The problem will arise when you know how to solve the question but it might take a really long time to work it out. Practice makes a man perfect. For algorithms, code every question you have tried to solve. Interviewers look for people who can write efficient and readable code. ["Use proper names for variables"]. When they ask you a question, they don't expect you to arrive at the exact solution. They look for the structure in your solution i.e have you considered the necessary parameters and does there exist a logical progression from one step to the next. If you are asked an open problem, don't panic. Keep asking questions to get a proper understanding of the problem and try to give them multiple solutions and reason out why each solution might be right or wrong.
