Duration: 1 hour
Total Questions: 30

Round: Test
Experience: The three questions are of three different levels.

1. You will be given two numbers. The first one is the starting point and the second one is the ending point of a range of integers. You have to count the number of integers in that range which are divisible by the first number.

Ex : INPUT : 3 18
OUTPUT : 6

2. You will be given a number. You have to find the sum of the digits. If the sum exceeds 9, you have to add the digits of the sum recursively until you a get a single digit sum.

EX : INPUT : 9999
OUTPUT : 9

Explanation: 9999 => 9 +9+9+9=36 => 3+6 =9

3. You will be given an array of characters which include ( L, R , or a number in the range '0' to '9'). A ball is kept on a line of integers initially kept at zero. The ball has to execute the instructions sequentially as follows:
(i) If an 'L' character is encountered, the ;position of the ball has to be decremented.
(ii) If an 'R' character is encountered, the position of the ball has to be incremented.
(iii) If an integer (in the range '0' to '9) is encountered , we have to go to that index in the array and execute the instruction present in that index.

Finally, after all the instructions are executed, you have to print the final position of the ball.

EX : INPUT :
Number of instruction : 5
Instructions: LR1R2

OUTPUT : 3

Explanation :
(i) Initially, the ball is at 0. Since the 0th index in the array is 'L' , the ball moves to 0-1= -1 position.
(ii) The 1st index is 'R' hence, the position of the ball is -1 +1 = 0 position.
(iii) The 2nd index is '1', hence we have to go to index 1 in the array which is 'R', hence the new position is 0+1 =1.
(iv) The 3rd index is 'R', hence the new position is 1 +1 =2.
(v) The 4th index is '2' , hence we have to go to 2nd index is '1' , hence we have to go again to 1st index , which is 'R' hence the final position is 2+1 =3.

Tips: We need to solve all the three the problems to have better chances of clearing this round.

Round: Interview
Experience: It was a general HR cum Case interview. 
I had done my internship in one of the analytics companies. So, he seemed interested in the project I had done. Then there was a case “I had to estimate the profitability of a car loan in the city of Texas. Given was the population of
Texas and the Loan amount. Any further data required was to be asked.
Tips: I had breezed through one of my mock interviews a couple of days ago. So I got a bit over confident and made calculation mistakes. These guys are edgy about calculation mistakes and don’t expect you to commit one. So be a bit careful while solving a case.

General Tips: I would like to start this article by telling you something about your major concern, and that is “Will this economic crisis has a telling effect on your job prospects ?”. And the answer is both Yes and No. I am a 5th year Mathematics student and have closely seen the placements of 3 batches and from my experience, I can surely say that “One who prepares well , gets through, No matter how tough the situation is". It happened with my batch and your batch won’t be an exception (Unless a catastrophe happens).


Dilemma:
Most of you guys sitting for placement shall be in your 7th semester which is considered to be one of the most hectic of all the semesters. Many of you might be preparing for CAT, others for GRE, some of you would have got a tough guide for your final year project. So you need to prioritize things. You need to think it through; “A Realistic Self Analysis” always helps. 
I’ll share what I did. I did join coaching classes for CAT but my first priority always was placements and accordingly I planned and executed things. Getting a 99+ percentile and then clearing the GD and PI’s was too much of a risk for me to take. So this might be one of the better times to go for your MBA but always have other options ready just in case.


Resume for Analytics Companies:
Most of the analytics companies have a lot of Statistical Analysis and Data Management work. So, candidates having an experience in Data handling are preferred. If some project of yours involved Data Handling, mention it in detail. If you have done some of the applied Statistics courses in the Maths/IME department, mention it in your resume.
