Difficulty in Answering Data Science Interview Questions

Hello everyone,

I recently came across an online data science interview questions resource and have been attempting to answer them. However, I am facing some difficulty in comprehending and answering some of the questions.

I have a good background in statistics and programming and have also completed some online data science courses. Despite that, I find some of the questions to be quite challenging.

I would really appreciate it if someone could provide me with some guidance on how to approach these questions or recommend some resources that can help me improve my skills.

Has anyone else faced similar difficulties while answering these questions? If so, how did you overcome them?

Thank you for your help.

Hi ashna, 

thanks for reaching out and sharing! I'd love to recommend some courses you can take, which answer some of the questions in the list. I'd recommend starting with:
Intro to Data and Data Science

Machine Learning in Python

Linear Algebra and Feature Selection

and Deep Learning with Tensorflow 2

I can also share with you my own experience starting in the field, also coming with a strong mathematical foundation and programming skills. At the beginning I found data science really vast and it felt as if it was impossible to learn and know everything, so I can understand your frustration on answering all the questions in the list. I can promise you that with time and experience it becomes a lot easier to navigate. My advice would be to take it one step at a time and start at the beginning. Once you can handle the fundamentals, it will be a lot easier to handle the rest. 

Best of luck,
