How to get basic knowledge in terms of mathematical analysis, working with data, building models as quickly as possible?

Question

IT education

Dear toasters, hello. Need your advice.
Mathematics was a favorite subject, he graduated from the faculty at the Kazan KAI, which is now called the "Institute of Computer Technologies and Information Protection", at the same time not yesterday, there are some initial programming skills in java. I never worked in my specialty, but at 30 I really wanted to. I really liked the internship of a data analyst, data sciense. hr asks for basic knowledge in terms of mathematical analysis, working with data, building models (as part of laboratory work or projects). What to watch / read, what course or textbook, please tell me

Answer 1

Lord, three questions a day, and everything is like a blueprint: "What to read in Data Science", "How to master Data Science as quickly as possible", "What you need to know in order to become a specialist in DS", etc.
My first the answer is - well, at least to learn on your own, at least on the same resource where you decided to ask the question, look for something that has already been answered to YOUR question before. You want to work with data, with information. Well, learn to look for information first!
And my second answer - here is the link directly "from under" your question:
Another question on AI and mathematics: what topics do you need to know?
Big AI learning algorithm?
Another question is how to get started in machine learning. How to start to understand whether I am interested in doing this or not?
Where to start learning artificial intelligence?
And here is the answer - straight from today's topic
What books for a beginner in Data Science?
In general - in the network of books, sites, courses, etc. - in bulk. For every taste, entry level and degree of learning. Choose to your taste - and go ahead.
Good luck.
