Interview Questions
- Q1. Why do you want to join EXL?
- Q2. How many 0's in 100!?
- Q3. Case study: Credit card fraud detection
- Q4. Applied Time Series ARIMA Modeling
- Q5. Some functions in R
Interview Preparation Tips
Round: Test
Experience: 45 questions and 60 mins. There is a Section wise cutoff. Manage time properly.
Tips: Prepare well from Pariksha.
Duration: 1 hour
Total Questions: 45
Round: Technical + HR Interview
Experience: Guesstimates and puzzles were asked in other panels. The guy in my panel asked about analytics project I did and the algorithm used. Afterwards he asked which topics I am proficient in. I did an Applied Time Series Analysis course and have experience in R. So he asked questions on ARIMA modelling and some functions in R. (dplyr package). Before going to the interview I only prepared for puzzles and guesstimates but not case studies. But he asked me a case study about the detection of fraud credit card transactions in a bank. I remained calm and cool without going into depression and suggested him some measures. Since the interviewer was also not looking for complex answers he got convinced with my answer. Then he asked me whether I have any questions.
Tips: Be thorough with your resume. Prepare puzzles and guesstimates. Case studies are simple. Just reading Case in point is more than sufficient. Practice guesstimates with your friends in free time everyday. Do the puzzles in 'Heard on the street'
Round: HR Interview
Experience: Since there was no time at the end my second round happened only for 10 min. Do complete research on EXL. This helps you in answering 'Why EXL?' question. Then he asked me how many zeros in 100!.
Tips: Be calm and composed. The interviewer gives you hints if you get stuck up anywhere. Get a early slot if possible. The people before me had 40 min second round interview whereas I only had a 10 min interview.
Skills: R, Analytical Skills, Case Studies, Math Puzzles

Interview Preparation Tips
Round: Test
Experience: Questions were based on C concepts, given piece of code, find error, output,etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Duration: 1 hour
Total Questions: 30
Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked what fields did you use in that structure, why this implementation and not some related other. Then questions on C concepts, memory allocation, function pointers, data structures, linked lists, then bit manipulation in registers. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Just be thorough with C (Know your Kernighan Ritchie) and be prepared to go into details about your projects.

5 Interview Rounds
Interview Questions
- Q1. Write a pseudo code to find the k'th largest element in a array
- Q2. A question based on expectation
- Q3. Another coding question(cannot remember which one)
- Q4. This round was completely based on probability and expectations. Asked 3-4 questions on expectations
- Q5. Probability and coding
Interview Preparation Tips
Round: Test
Experience: There were total 10 multiple choice questions and 4 subjective questions.
The MCQ's were based on Probability and expectation.
The descriptive were based on
1. Number Theory
2. Puzzle
3. Coding (Need not write compilable version but write a clear pseudo code).
4. Coding(Same as above).
Solve puzzles in heard on the street and day 1.0 book. Finish the course Data Structures and Algorithms.
Tips: Must correctly solve atleast 9 of the probability MCQ to ensure a final interview shortlist.
Duration: 1 hour 20 minutes
Total Questions: 14
Round: Technical Interview
Experience: He asks you write a pseudo code for the question asked. You must write a clear working algorithm. If you make small mistakes, he will try and correct you but huge algorithm errors can cost you the call for next round.Remember to give correct time complexities for the algorithm written. Be clear and try to explain your thinking process to the interviewer. If you are stuck, try to explain your idea and where you are stuck. He will help you move further. The whole interview lasted around 40-45 mins.
Tips: Maintaining communication with the interviewer is very important. Asked reason for low CGPA (mine was 7.94).
Round: Technical Interview
Experience: One o the question was - If you break a stick of unit length into two parts then what is the expected length of the longer part. A few others to calculate mean and standard deviations etc.
Tips: Must communicate with the interviewer and show him your arrival at the solution. They usually respond positively if you give them the correct answer. If you make a mistake, will give you a small hint to correct yourself but if you still make it, then you're out. If you are good with stochastic processes , then it would definitely increase your chances of progression.
Round: Technical Interview
Experience: Started with asking about favourite coding language. Chose Java , then asked basic questions like what is static class and what is it used for (OOPS concepts). Asked a few probability questions and then a few DSA questions.
Tips: Was bad in a section( I could not answer OOPS questions)but still gave me a chance again. If you recover from it and answer remaining correctly then you get to go to the HR round.
Round: HR Interview
Experience: Telephonic interview and was asked few questions about myself like education, Family background, Why job instead of higher studies, why job in finance and specifically Quantitative research, future plans etc.
Tips: This was not really tough. The HR also tried to explain what the job was about. They confirmed the Job Offer within 5 minutes after the phone call ended.
Skills: Coding Skills And Knowledge On Data Structures, Probability And Statistics, Solving Logic Puzzles

Interview Preparation Tips
Round: Technical Interview
Experience: I got stuck in the question as I wasn't able to approach this question. The interviewer helped me out by giving me the following two clues.
1. Two properties of MST : Cycle Property and Min-Cut Property.
2. 4 cases : (modified edge in old MST)*(weight increased or decreased) -> I eliminated two cases as it would return the old MST. Only 10 and 01 need to be considered.
Tips: Requires Graph Theory(Min Spanning Tree algorithm, Min Spanning Tree properties etc.)
Round: Technical Interview
Experience: I had no idea to approach this problem.
I decided to first come up with an algorithm to obtain the maximal transitive sub-tournament given a tournament.
The interviewer then told me to see if I can upper bound the minimum out-degree in a tournament.
After this, the solution was to upper bound the minimum size of the transitive sub-tournament.
HINT : Use the fact that a tournament contains N_choose_2 number of edges for part II.
Tips: Requires very little graph theory. More thinking based, proof oriented. I had to prove every claim I made.
Skills: Graph Theory, Logical And Structured Thinking, Proving Abilitites
