Incredibly bad book. Does not appear to be written by a native English speaker. Lots of errors - both substantive and editorial.

Best Interview Guide for Data Scientists

Reviewed in the United States 🇺🇸 on April 16, 2022

Verified Purchase

I have always been nervous when going to interviews for the fear of not being sufficiently prepared. As a Data Scientist, I need to grasp knowledge about a myriad of subjects such as programming, database management, and machine learning; and practicing all these for an interview is very overwhelming. I found this book to be very helpful in providing me with an effective study guide to ensure I learn all the important concepts and increase my chances of passing the interview. More importantly, the questions are compiled from data scientists working in my dream companies including NASA, Google, Amazon, and Facebook, thereby making the book befit the context of the real world. If you are going for a big science interview and you are having some doubts or feeling nervous, make sure to buy this book.

I found this book to be really helpful when prepping for interviews. It covers foundational concepts clearly & concisely. What I found most helpful though were the case studies that had step-by-step walkthroughs of the solutions.

I really liked this book. I wanted to prepare for tech interviews, but I actually learned a lot of practical stuff about design that I didn't know I needed to learn.
