I've been a data scientist for over three years, so I want to write a post answering the most popular data science questions I've received in the comments section of my YouTube channel and in Medium articles.
The questions are structured into technical, professional and then various advice. I hope you find what you are looking for!
To what extent should I know SQL?
SQL is a fundamental language for a data scientist, so you must know it well. The good thing about SQL is that it is much easier to learn than Python because it is a very small language.
I have an article that explains the exact SQL knowledge you need to be a good entry-level and mid-level data scientist and I recommend you check it out.
