How to Crack Mu Sigma Interview For Trainee Decision Scientist

Follow the below strategy step by step easily crack Mu Sigma Interview:

There are 4 rounds of interview in Mu Sigma:

  1. Aptitude Test
  2. Group Discussion
  3. Technical interview
  4. HR round

1st round: Aptitude Test

The  Mu Sigma Aptitude and Personality Test evaluates you on your aptitude, quant, and logic, language, and communication, personality and creativity. It is a kind of psychometric test designed to evaluate your aptitude, what kind of a person you are and how you would react in different situations.

It is divided into 4 parts.

  • Quantitative Aptitude and Logic
  • Language and Communication
  • Personality and Creativity
  • Video Synthesis
  1. Quantitative Aptitude and Logic: Study the basics of quantitative aptitude and logic like reasoning, conditional statements, etc. You can refer to the Quantitative Aptitude by RS Agrawal.
  2. Language and Communication: Improve your vocabulary and focus on Grammar while preparing for this section. I think the most important part will be Grammar and spoken communication.
  3. Personality and Creativity: There is no way to prepare for this section as there are no right answers to any of the questions. Every person is different in his/her own way and that’s good. My only advice would be to not fake your personality or try to portray a different self as they will easily call your bluff in subsequent rounds. They are not looking for any specific kind of people so it’s good to be you.
  4. Video Synthesis:

     In this round, you will be shown a video clip and you will have to write your own synthesis of it in 4-5 sentences. The purpose of this round is to see your ability to make sense of the data you are presented with beyond just summarizing what is shown.

    A few tips for this round:

    1. Don’t, just don’t write a summary of what you saw. This is a strict no and will be rejected outright.
    2. The video clip will be in English and mostly without subtitles. They will play it only once whether you got it or not. So be prepared and pay full attention.
    3. Try to add your perspective on the scene. You don’t necessarily have to agree or support what is shown in the video. But if you are opposing the idea, do so with strong points and you’ll surely be noticed.
    4. Write crisp and short points and be as precise as possible, long sentences generally show that your thoughts are not clear and are prone to rejection.
    5. Try to add an original perspective to the events of the video as to why it could be happening or what could be the impact, etc.


There is not much preparation you can do for this section other than trying to write a short synthesis of different things you read/watch every day.

2nd Round: Group Discussion

The applicants will be made to discuss some topic related to data analytics and its present state. You are not expected to know a lot about the topics. The evaluation criteria are based on your communication skills and clarity of thought.
You should prepare by practicing regularly to speak in English on random subjects and also by learning tricks of making an impact in a GD and different GD etiquette like when to interrupt, how to speak and what to do and what not to do.

3rd round: Technical interview

  •  Prepare all the skills which you have mentioned in your resume.
  • Prepare SQL,
  • Data warehousing concept(OLAP, OLTP, Snow flake schema, star schema ER Diagram, data moeling)
  • Data Analytics concepts ( Recommanded)

The Mu Sigma Trainee Decision Scientist interview mostly focuses on understanding your personality, your specific skills and how truthful were you in your Aptitude and resume.The key differentiator in this interview will be the focus on your answers in 1st round of interview. The interviewer will ask you to justify your answers in the test to various questions and also ask you to explain why you answered in a particular way. The key here is to not fake or cheat on the test because they will easily find that out in the interview.

The other part will be focused on your video synthesis answers. The interviewer might ask you to elaborate on the points you wrote about the video in your answers and also ask you to explain your stand why you feel so. They will test your deduction skills here to see if you could really make sense of the video or data that was presented to you.

4thround: HR round

  • Prepare your self-introduction
  • Why Mu Sigma
  • What you know about Mu Sigma

Lastly, they might try to see how much you know about the company and ask you if you have any questions for them. This is major to see your interest in joining the company and your knowledge about the company you want to join.

While the first two sections will definitely be there, the last two are optional and the interviewer might ask you these questions based on how you fare in the first two sections.

Be prepared to answer questions about your projects, academics and other activities and certifications.  Asking a few questions about the company that you couldn’t find answers to on the internet also casts an impression that you are interested in the company.
