Data science is exploding in practically every corner of the globe. With the growing popularity of data science and machine learning, more aspirants are interested in learning more about these subjects and landing jobs in the field. And as we know, giving interviews is a nerve-wracking chore. 

Data scientists are in high demand because of their magical capacity to extract value from data. As a result, data science opportunities are anticipated to grow 36 percent from 2021 to 2031, which is faster than the average for all other occupations.

So here are the top websites/platforms that help you prepare for that data science interview.


An essential step while planning for a data science interview is to test yourself. MachineHack offers mock interviews that consist of several short and long mock data science interviews to assist you with measuring your standing.  The platform offers packs for organisations like AWS, Microsoft, and Google, for different data science positions like data scientist, associate data scientist, deep learning engineer, and more.
