Data Science is a multidisciplinary which involves Computer Science, Mathematics, Statistics and Domain Knowledge. Preparation for an interview in data science would require knowledge and expertise in a subset of the above disciplines. To summarize one would require skills on Algorithms, SQL, Probability, Statistics, Econometrics, Problem Solving, Machine Learning, Optimization, storytelling and presentation skills. In this course, I would cover few questions on Probability, Statistics and different aspects of Machine Learning. This course can act as a quick preparatory guide to kick start your preparation for a data science interview.
