Q&A

  • Please tell us about your typical day at work as Senior Data Scientist.

My typical day at work starts with me looking at my project tracker – a simple document where I keep track of my short and long term projects. At any point in time, I am working on one long term project and one or two short term analysis type projects. I am also responsible for the performance of my team of 4 Analysts.

Steps in my work involve:-

  1. breaking down an abstract problem into actionable sub problems with goals
  2. extracting and cleansing the data
  3. doing extensive Exploratory Data Analysis (EDA)
  4. writing optimized and scalable code to build models
  5. measuring performance or arriving at inference
  6. finally presenting the results to business stakeholders
  • You have been working in Data Science Analytics consulting field from past 8 years. What advice would you give to students aspiring to work in this field?

Data Science consulting gives you opportunities to work on diverse set of problems. In my last 4 years, I have almost worked with most of the tech and retail giants in the Silicon Valley. You get to work with the best minds in their respective domains, but here is the catch, you are always expected to bring something new to the table. In my experience, I always felt that many a time clients hired one of us so we could provide them a fresh perspective. As a consultant you are paid by the hour, hence you always have to be on your toes, be extra prepared for the meetings. All in all you always have to be a step ahead than the rest of your product team members.

Last 4 years consulting for 10 different fortune 100 companies and 3 different emerging and high potential start- ups in the bay area taught me three great mantras-

  1. Fail Fast → Philosophy of incremental development. Cut losses when something isn’t working and quickly pivot to something new.
  2. Move Fast → Let’s say a particular problem deals with 5 lines of businesses (LOB’s) and let’s say lob A and B alone account for 85% of the business and lob A alone accounts for 60% of the revenues. I / My team would immediately go after LOB A, let’s say building a forecasting model to predict demand – supply in that lob or building an inference model to understand the $ value of a customer moving through different funnel stages in that lob. My point being solve for that 60% module, validate and report results. So that the business stakeholders have something to hold on to or plan for at least for that lob in the short term while you try to figure out the entire problem and solve for the same.
  3. Ask the right questions and always question the status quo.
  • How is working in US different than working in India?

I get to work with a diverse set of people in the US. Diversity in a team / company has huge benefits. I have been on projects where data scientists and behavioral scientists have worked together. I had the opportunity to have worked with a head chef on scenario planning regarding which cuisines the culinary team should go for on which days of the week to maximize coupon sales in the office kitchens. So to summarize in one word – Diversity.

  • What role did Great Lakes play in shaping your career?

I owe a tremendous lot to my Professors at Great Lakes. Every single class in the curriculum, right from Statistics to Economics to Ethics to Risk Management was important. I specifically want to thank a few of them whose classes I enjoyed thoroughly.

  1. Prof. Bappaditya Mukhopadhyay – Bappa sir as we call him. I adore him for his simplicity, he instilled in us one important thing – “Learning from First Principles”. First Principles thinking enables you to discover unconventional insights based on fundamental truths. We basically boil things down to fundamental truth and then reason up from there.
  2. Prof. T.N. Swaminathan – When the startup I joined post my graduation was going through some tumultuous times. I wrote to Prof Swaminathan saying I was finding it difficult to go after the positions / roles I aspired for, because my work experience was less. He immediately opened up his contacts. That was a pleasant gesture from him. He didn’t have to personally vouch for me but he did, getting the right opportunity at the right time is very difficult many a times, Prof Swaminathan gave me one and I utilized it to the fullest then.
  3. Prof Veeravalli’s class on Entrepreneurship was important at many levels. If your client is a startup or a new strategic business unit in a big firm, many a time you don’t have huge volumes of data. Your thinking needs to be a bit different in these scenarios. The metrics you go after for optimizing or predicting become much more basic. His classes already taught us these things so I didn’t have to learn it the hard way.
  • What advice would you give to Great Lakers?

I would advise them to go after the roles one desires or the ones that give them immense pleasure instead of just looking at the pay-packet size. The lessons from the curriculum and the experiences you earn will always come in handy both in the short and long term.

  • What do you do in your free time?

I developed an interest for Chess late in my life. I am currently ranked around ~1950 levels in rapids. I also play tennis on the weekends.

Understanding Analytics and Data Science in the IT Consulting Landscape


Mr. Arindam Mukhopadhyay,
Vice President & Global Head of Consulting COE, Gartner

Studying at Great lakes, Gurgaon brings unique experiences for Jaguars every day. Adding further to our enriching experience, we recently had a very exciting session with the Team Gartner. The speakers including Mr. Arindam Mukhopadhyay, VP & Global Head of Consulting COE, Mr. Sushant Mondal , Sr. Consultant and Mr. Ravi Anand, Campus Recruiter explained the topic and also spoke on  how Gartner functions for providing consultation to the IT Companies.

Beginning the session, a student introduced our guests to the audience stating their achievements, which left us Great Lakers in awe. Excited at the opportunity to learn from the best, the students welcomed our guests with a huge round of applause. Kicking off the talk for the day, Mr. Ravi gave a brief outline of the talk. He then handed over the mic to Mr. Arindam who introduced the students to Gartner and the ideals and ethics the company was built around. He then elaborated upon the various industries that Gartner provided its consulting to, customer service and support, finance, marketing and sales, research and development, etc. being a few of them. The consulting prowess of Gartner was made clear and it was welcomed as such by the eager audience.

“Trusted insights, strategic advice and practical solutions, is what Gartner offers its clientele.”, said Mr. Arindam. “Who do we serve? And “What do we do?” were the questions that flashed on the projector screen, the answers to which were extensive and exhaustive in nature. Leaving no bits out, Mr. Arindam helped create a mental image about Gartner, about what they do and how they go about doing it and finally he addressed what being an employee at Gartner entails. With this he ended his talk and called upon Mr. Sushant to take over the talk.

Mr. Sushant Mondal,
Senior Consultant, Gartner

Mr. Sushant,senior consultant at Gartner immediately won over the crowd with his smiling face and sweet demeanour. He began his part of the lecture with a question,“What is AI?”, to which he got numerous answers from the informed crowd. Welcoming all the responses, he added “The bare bones definition of AI could be,automation of something that a human can do.” The talk then briefly ventured into what AI can be in the future and how and when it will surpass the intelligence of humans. Coming back to the present, our jolly guest explained to the students the hows’ and whats’ of data. “Data is generated in huge amounts but the inferences that can and should come through the data are absent. This is where Gartner comes in. We analyse the data, provide actionable insights to the clients and help solve their business problems”, said Mr. Sushant. Adding to it he continued, “Most consultants end their work here, but at Gartner we also help with the execution of these strategies if the company desires it.”

Moving forward, Mr. Sushant gave intricate details about the processes that are followed by Gartner to provide the best possible consultation to their clientele. He then gave a few real-life examples of how Gartner had helped companies from different industries like healthcare, pension fund and manufacturing. An impromptu case was presented to the students from them to work upon in a way similar to how Gartner would, the solutions to which were then discussed.

This was indeed an extremely informative and detailed lecture by Gartner, the likes of which our Jaguars had not experienced. We are thankful to Gartner for dedicating their resources for our students, who left the auditorium which was beaming with gratitude.

Analytics and Artificial Intelligence: An enlightening session with Mr. Jaidev Deshpande

GREAT LAKES GUEST LECTURE SERIES

Mr. Jaidev Deshpande

Senior Data Scientist, Gramener

Picture this, you’ve just had a scrumptious meal and you’re now back at your desk. The mirage of a soft bed and a warm pillow invites you to indulge in a little afternoon siesta. Your eyes feel heavy already. But if you’re a Great Laker, it would rather be a different story altogether. The ever-energetic Jaguars (and Aztecs) of Great Lakes Institute of Management, Gurgaon, had suited-up and gathered in the auditorium for an interesting take at Analytics and Artificial Intelligence by Mr. Jaidev Deshpande, Senior Data Scientist, Gramener, orgainzed at the campus recently. Taking the eager and curious students on a journey, our storyteller opened the talk with a brief introduction of what data analytics entails. He started off by displaying a beautiful image of ice-capped mountain ranges and asked the students to find out what’s wrong about the picture. A light murmur rang throughout the room as the students put their grey-matter to use, one of the attendees was able to identify that the peaks were extraordinarily pointed. Impressed, Mr. Jaidev said, “You are correct, the mountains are superimposed on a graph, of the US 2008 Recession to be precise.”

Moving on, he took the students on a virtual tour of the work he and his team had performed and the pinnacles they had achieved over time. He won over the enthusiastic students with the mind-boggling inferences and patterns that can come out of the data. “Nothing is random”, as Mr. Jaidev would like to state, is quite true in a practical sense. In order to drive his point home, he had a few students come up to the podium and arrange themselves randomly. Well, randomness was just an illusion, as the students were smitten when he explained that even that randomness had a pattern, which manifested itself on close observation.

The next part of his talk emphasised on knowing how to think, in terms of System 1 and System 2 thinking. Establishing references to the seminal work, “Thinking, Fast and Slow” by Daniel Kahneman, Mr. Jaidev explained the concept of “Availability Heuristic” through real life examples from his own personal and professional life. He further explained the significant hindrance that biases can have on the pattern recognition in data. Again, to illustrate his point, Mr. Jaidev engaged the students in identifying patterns in certain charts and data visualizations. His hypothesis was immediately confirmed and he concluded saying, “As soon as you see data, you try and find patterns in it. But these patterns are biased and you miss out on the bigger picture.”

Mr. Jaidev delivered a truly eye-opening and awe-inspiring perspective to analytics. The session went beyond just a classroom session and compelled the students to consider the infinite possibilities which they had not fathomed so far. Great Lakes Institute of Management, Gurgaon expresses its heartfelt gratitude to Mr. Jaidev for taking his time out and enlightening the curious Great Lakers with lessons that will last for a lifetime.
