Experience: The questions asked from all the candidates in all the rounds were quite similar in nature. They were asking puzzles, numerical reasoning based questions and things which would require use of your analytical skills. The questions weren’t difficult and one can easily find them on placement preparation sites. They also tested me on my knowledge of core engineering subjects to ascertain whether I am serious about the tasks I have in hand.

They also asked few normal HR questions. Some of them were about my short term and long term goals and where do I see myself after three years. They also asked me the reason for shift to a non-core field company.

Round: Resume Shortlist
Experience: I used only one resume for all the companies that I applied in. I mentioned about my extra-curricular activities and my projects with the projects relevant to the profile on offer getting higher priority.

Round: Test
Experience: For the aptitude questions the preparations for the CAT examination that I had done earlier in the year proved to be availing. Whereas for the technical questions I studied topics like fluid machinery and IC engines.

The first round in Mu Sigma was the aptitude test. The test pattern was CAT based, but the difficulty level was pretty mediocre compared to CAT papers.
Tips: There was time constraint in the test. Therefore I would recommend you to practise some questions before appearing for the test to improve your speed.

Round: HR Interview
Experience: The interview began by the interviewer asking me some HR questions. The last question I responded saying that Mu Sigma is company catering to the needs of solution seeking companies. To this the interview asked me come up with a problem that I felt the company would have to deal with and also an efficient solution to the same. I designed a problem which was related to the loss in sales of Refrigerator and I solved it using the 4P concept. Then they asked me a puzzle which was that in a room of height 100m to ropes are hanging one of 120m and another of 60m and your height is 10m then what is the maximum length of rope that you can cut.

College Name: IIT ROORKEE
Motivation: Mu Sigma is a company that deals with data so I went through their site and found what it does. Later the other queries related to the company were cleared by attending the pre placement talk.

Total Questions: 15

Round: Problem Statement
Experience: Learn the basics of a programming language. The problem solving round involved a psuedocode .For the video synthesis round question of our batch, Google "Toast for change" , there is a 5 minute video clipping and we were asked to synthesize it ( NOT summarize it!!! )

Round: Group Discussion
Experience: The gd consisted of two sections. In the first section the students had to discuss the points to be considered while selecting a website. Some of the points we had put up included the site should provide tour packages which is favoured by a lot of people, the site should be linked to applications like Google maps which can provide access to information like location etc,
During the second part of the gd, the students were given five minutes to discuss and decide 3 main points out of all the points discussed previously.
After the gd, the students were asked to 1) write down all the points discussed in the sheets provided 2) write down all the points which they have not mentioned during the gd but are relevant the topic
Tips: 1) Use the time given to think properly. A proper set of points goes a long way in improving your performance during the gd
2) Read newspapers and articles on such topics. Will give an idea about such management issues
3) Be loud. Makes one look more confident
4) Listen to what the others have to say. The judging panel looks for a good speaker and a good listener. The advantage is twofold: firstly if you are out of points you can simply get something to speak about by combining what the others are saying and contradicting a few other like "I completely agree to what so and so have said but I would'nt quite agree to this because .....". The judges will note you as a good observer
5) Donot dominate over others. A group discussion is not a debate where you have to take a side.
6) try to add numbers and statistics in the discussion cause that's what analytics company want from their employees

Round: HR Interview
Experience: The HR PI was quite casual, slightly informal. I was asked about family members etc, followed by a question about the reason for my drop year. The first question after the introduction was "tell me about yourself". This question can be predicted as "tell me about your qualities that make you fit for our company". I used this question to describe all the traits that made me suitable for them, and normally I justify each quality I mention immediately. Also I would advise you to emphasize qualities that set you apart from the crowd and make you fit for their company. The HR asked me why I intended to join an analytics company if all my projects were based on biomedical. My answer to the question was that my projects were all soft computing based, and hence most of the work I do involves using a set of data to predict something which is quite similar to what they do in Mu Sigma. The only difference lies in the fact that the work I do is based on bioloigical data and biological parameters and they used market and business data( please note that I could only bring this up since most of my work is based on neural networks and soft computing, please do prepare something to relate what you have done to what they do or simply mention you were always interested in analytics and playing with nos from the start).
I was asked about a few projects of mine mentioned in my CV, I was asked to explain them, I was asked a few questions on neural networks(they only asked them cause I had mentioned it earlier)
In the end the HR asked me if there is anything I would like to ask him, so I asked him to criticize me so I could work on the points where I lack. He gave me 2 points.
Tips: Points to be noted about the hr pi:
1) Observe the nature and personality of the PI. The video presentation at the beginning of the placement process gives a very good idea about the hr's personality, the work culture etc. So use this information to predict his nature and present yourself accordingly
2) Relax. In my opinion the hr PI is the easiest and the most fun round in Mu Sigma.
3) Use the tell me about yourself and the free question well. What you ask and what you say will give a very good glimpse of your true personality
4) There is no need to be very formal and robotic but maintain politeness while answering.

Skill Tips: 1) Improve your aptitude solving ability.2) Learn the basics of a programming language. The problem solving round involved a psuedocode.3) For the video synthesis round question of our batch, Google "Toast for change" , there is a 5 minute video clipping and we were asked to synthesize it ( NOT summarize it!!! )
College Name: NIT RAIPUR

Round: Test
Experience: The questions were of medium to high difficulty. What set this test apart was the fact that each question had different weightage ranging from 0.5 to 3 marks per question. Time was a major factor. So my strategy was to attempt all the 1 and 1.5 marks questions which constitute the major chunk of the paper in around 40 minutes and spend the remaining 20 minutes for the 2 and 3 mark questions. I did not even bother reading the 0.5 mark questions. The 2 and 3 mark questions were difficult and those will differentiate you from others. 1600 students wrote the test and only 86 got shortlisted for the next round.
Duration: 60 minutes
Total Questions: 40

Round: Technical Interview
Experience: I was asked to write a C program to print the Fibonacci sequence and a basic SQL query. Apart from this I was asked a puzzle and other questions related to my resume. Out of the 86, only 26 students were called for the next round which again was a technical interview.

Round: Technical Interview
Experience: This was similar to the first technical interview. I had to write a C program to print the prime numbers between 1 and 100 and a puzzle was asked again. Apart from this a guesstimate to find the number of cars between 2 places was asked and a scenario based question too was asked. These were followed by resume related questions.

Round: HR Interview
Experience: All the 26 students who attended the second technical round were allowed to attend HR round as well. This was just for 4 - 5 minutes. I was asked about my family background and why I should be hired. My fondest memories from school days were asked too. Finally offer letter was given to 10 students out of the 1600 who wrote the test :P

General Tips: Just keep a calm head and attempt the questions. Ask for time to think if you are not able to answer the questions immediately. Be bold and confident. That is sufficient :)
Skills: Puzzle Solving Capability, Ability To Think, SQL, C Programming
