I agree with you that the Masters that I want to study at ESSEC is completely different from what I have done so far. How did I come to do this? One of the primary reasons why I chose this path was because of my brother. I decided to follow the path that my brother took: he also holds a Masters in Philosophy and had decided to make a complete switch by following a Masters in Data Science at London Business School.
Being a student of LSE I had the opportunity to visit LBS on several occasions where I noticed that the MIM, even though it is a very interesting program, would bring me far more than a Masters in Data Science would give me, as the Masters in Data Science will be a completely new program for me and I will need to begin with the basics.
However, I believe that this new experience will be helpful for me in the long run and will complement my first training.
Secondly, what appealed to me was the challenge. I am a student of social science with a very limited scientific background. I want to understand the world around me including computer science, programming, machine learning etc, and I realized that this degree will be exactly the type of thing that can teach me all that I want to know.
Finally, I also believe that in the current scenario there are very few people with this type of degree and it is something that is also really appreciated by companies.
