Regarding the topic, a lot many problems were discussed like intracity traffic, transportation, women empowerment, education etc. People got enough opportunity for asking cross question and also people handled cross questions maturely.
Tips: Try to think through multiple dimensions, don't restrict yourself to some specific domain. To generate points u can use SPELT method i.e. try to get points considering Social, Political, Economical, Legal and Technical aspects of an issue. Dont get aggresive give chance to others also to make their point. If you don't have your own points then also don't remain silent, try to add new dimension to the points made by other people.

Round: Test
Experience: It was a very different and exiting test as compared to other company aptitude tests. It was more of a fun test rather than a quant test. Negative marking was present. The test was divided into two parts: 60 mins and 30 mins.
The 60 mins part consisted of 4 sections:
1. Quant and Logic
2. Language
3. Creativity
4. Personality Assessment
Here, you need to use your time well. You can switch between these sections.
Quant was only 10 questions, which were quite easy.Main questions were based on Number theory, probability, profit & loss.
Then there were logical reasoning questions where you need to put in proper thinking, which requires time. Personality assessment had tricky questions like "would you lie for the company", "would you use office stationery for personal home use", "What is the joke made of you often and how would you rate it?".Answered these quickly and truly.
The 30 mins part also consisted of 2 sections:
1. DATA ANALYSIS(Write what all you infer from the given table)
2. Picture description(What do you infer from the image below)
These sections were very easy. No preparation required as such. Just apply the common sense and linguistic skills. Make sure grammar is correct. Be precise. Long essay not required.
Tips: Do not panic.
The time alloted is plenty. Use it well.
Most of the Personality assessment and quant questions had come from the Mu Sigma sample question list, which is available online through mu apt.
Answer only those questions which you are sure about.

Round: Video Synthesis
Experience: A video will be played for 17 minutes. The requirement was to note down in points, what I had inferred from the video. The video played would be of any genre. It may be a short inspirational movie scene or the CEO lecture. For me, it was a promotional and summarizing lecture given by the CEO. I was given 10 minutes and I had to write what I had inferred from the video on a small card, provided by the recruiters.
Tips: Note here that it was expected that we write 3 main takeaways and NOT the summary. Do not fill the card with an essay. Put down three strong bullet points. Do not write what was already there in the video.


Round: Group Discussion
Experience: We were a group of 10 and the GD went on for about 20 minutes.We were told that we would be judged on how much we speak, our understanding of the topic, the amount of factual data we put in etc. The recruiter was observing us all the time and noting down his observations,each time we said a point. At the end of the discussion, the recruiter himself stopped us and asked each one of us to conclude the discussion.
Tips: 1) Use the time given to think properly and formulate proper set of points.
2) Stick to your points and put them forward convincingly.
3) Be loud and confident. Look at your group members while speaking and not at the recruiter.
4) Listen to what the others have to say. Make a mental/written note of all the relevant points discussed, which will help you while concluding. If you disagree with anyone's point, convey it politely.
5) Do not dominate over others.
Duration: 20 minutes

Round: HR Interview
Experience: My personal interview was a combination of HR and a bit of technical. Basic questions like "tell me about yourself", "hobbies", "tell me about your family","are your comfortable coming to Bangalore", "what do you feel about our package" were asked. Apart from that, I was asked how many branches does my college have, Why I chose Information Technology, Which subjects are different between Computer Engineering and Information Technology. The recruiter also asked me what was my favorite subject. He told me to introduce the contents of the subject to him and asked a few technical questions on it. I was also asked "If I am the store manager of McDonald's what will be the day to day decisions I will be taking?". I had already thought of an answer for this question since I had read it on ambition box before the interview day. I thank ambition box for making me acquainted with it.
Tips: 1. Relax. If you have reached this level, you have very high probability of being selected. PI is the easiest and the most fun round in Mu Sigma.
2. Use the "tell me about yourself" as a star question. Cover all the basic things like Name, current ongoing education/job details, strengths, weaknesses, hobbies, family introduction, your goals and your values.
3. There is no need to be very formal but maintain politeness and honesty while answering.
4. Be sure that you know why you want to work with an Analytics company. Specially if you are a coder, they ask you why you chose Analytics over Software development.
