3 Books for Data Scientist Interviews

Recently I made an infograph to show my classmates' current companies. I graduated with a M.S. in Business Analytics in 2014. A lot of my classmates pursued their careers in Data Science. 5 years ago, business analytics or data science were not considered as a major at college. It's a emerging subject that calls programming and statistics together to find the story of big data.
