Not only was he well-versed and practiced in the fundamentals and advanced techniques of Data Science, he was also driven to help me succeed. He relied on his mastery of the content and strong communication skills to explain complex concepts in a clear and applicable way. His punctuality and organization is second to none. He is an outstanding asset any organization would be lucky to have as part of their team. " and "Arnab is one of the best teachers/mentors I have come across over the years. Our relationship started as I was a data science student fortunate enough to have Arnab be selected to be my mentor. From our first meeting, I could tell I was very lucky. Arnab did not take the traditional approach of diving into what he thought was key, he took time to understand me as a person, my aspirations, learning style, and more. And what's even better? He used this information to guide our chats - from candid conversations about the day-to-day of data-focused careers (data scientist, data analyst, sales analyst, etc), business possibilities within the space, career guidance, and even technical troubleshooting. It was amazing to me that Arnab was able to relate to me and ensure that I learned in the most effective way possible. He is clearly a very talented data scientist, but what is more impressive to me is his mastery of soft-skills that many technical individuals haven't developed as well. He is a very well-rounded leader and I am confident that he will be successful in any future endeavor! "
