Master data science concepts!
Extremely HandsOn... Incredibly Practical... Unbelievably Real!
This is not one of those fluffy classes where everything works out just the way it should and your training is smooth sailing. This course throws you into the deep end.
In this course you WILL experience firsthand all of the PAIN a Data Scientist goes through on a daily basis. Corrupt data, anomalies, irregularities  you name it!
This course is for anyone who wants questions to practice for their next Data Science Interviews or want to test the understanding of their concepts.
The course covers a vast range of topics from probability and statistics to Data Science and Machine Learning Algorithms. This course doesn't waste your valuable time.
If you do not get the answers to a question, you can understand how to solve them from our welldetailed explanations.
Also, please note that the course will be updated in the near future.
This is the most comprehensive Test Series online which will help you ace your Data Science/Machine Learning interviews.
Being a data scientist is one of the most lucrative and future proof careers with Glassdoor naming it the best job in America for the third consecutive year in a row with great future growth prospects and a median base salary of $110,000. I have recently made the transition from being a PhD student in Computer Science to a Senior Data Scientist at a large tech company. In this course I give you all the questions and answers that I used to prepare for my data science interviews as well as the questions and answers that I now expect when I am giving interviews to potential data science candidates. The course provides a complete list of 150+ questions and answers that you can expects in a typical data science interview including questions on machine learning, neural networks and deep learning, statistics, practical experience, big data technologies, SQL, computer science, culture fit, questions for the interviewer and brainteasers.

Data Science 101
Put simply, data science refers to the practice of getting actionable insights from raw data. Our guide will walk you through the ins and outs of the data science field, including how it works and examples of how it's being used today.
 An AIgenerated text prediction model was trained to write a Harry Potter novel.
 The earliest case of data visualization being used to influence public policy was around getting better sanitary conditions for British soldiers.
It is better to be honest and admit that you don't know than to try and make up an answer. The interviewer will be more impressed if you can demonstrate that you are willing to learn new things. Remember, the best way to prepare for a data scientist interview is to practice as many questions as possible!
