About the Book
The demand for skilled data scientists in industry, academia, and government is rapidly growing. This book provides conceptual solutions to questions asked in data science interviews at top-notch companies. It spans probability, statistics, linear algebra, matrix calculus, machine learning, deep learning, tools and other relevant skills.
The present work will serve as a complete guide to professionals reading the subject with few or no opportunities of instruction. This will save the time and lighten the work of interviewers as well. This book helps in acquiring a better understanding of the basic principles of data science and in revising a large amount of the subject matter quickly.
Care has been taken, as in the forthcoming ones, to present the solutions with multi-concepts and beyond in a simple natural manner, in order to meet the difficulties which are most likely to arise, and to render the work intelligible and instructive.
This work contains several variations of problems, solutions, methods, approaches to enrich, strengthen and enliven the inherent multi-concepts.
