CS Knowledge Interview
How should I prepare? 💬
CS knowledge refers to design patterns, networks, operating systems, databases, and data structures. There was a problem that there was too much to study in specialized books, and there were many times when I got confused because there was incorrect knowledge when I studied online.
To solve such problems, I wrote a book called "CS Major Knowledge Notes for Interviews" and created a lecture that can finish CS knowledge in one go based on the contents of this book and important contents that are not in the book.
No. 1 bestseller in IT in Korea!
The best book explaining CS major knowledge in Korea

A whole 24 hours!!
You can finish CS knowledge with this one lecture.
I want to finish everything about "CS knowledge" with this one lecture . I'm sorry, but you can't prepare 100% for CS interviews by only studying past questions. I don't just study past questions, but also the core basic concepts of CS, and in-depth knowledge to prepare for follow-up questions. I want to say that this is the right way to study CS knowledge.
A total of 500 pages
Amazing teaching materials provided! 😎
We provide a total of 500 pages of lecture materials that cover the essential elements of CS knowledge, from essential developer knowledge to databases, operating systems, and interview tips. Through this, we have tried to cover the entire CS knowledge content in one lecture.
The contents of the lesson are as follows.
In the case of differences that are frequently asked in interviews, they are organized into a neat table.
Terms that may be confusing or require further explanation are organized in [Appendix].
A clear explanation of the confusing REST API.
This is a frequently asked question and a way to build a shopping mall ERD with deep knowledge.
Usually, when explaining JWT tokens in lectures, we explain using only one JWT token, but in practice, when using JWT, authentication logic is performed based on two tokens: an access token and a refresh token. This is the most correct way to explain it.
A practical example of practicing JWT token authentication logic using simple yet quality code suitable for practical use.
An explanation with fun pictures that will stay in your memory for a long time.

Study based on importance!
If you don't have time, you can just listen to the lectures with high importance! It's better to listen to all the lectures, but... for those who are cramming, I've ranked the importance based on the star rating.
No more studying countless textbooks
I want to avoid having to study by scouring the Internet.
Don't waste your time
I hope that you will be able to finish your interview regarding "CS knowledge" with this one lecture.
The curriculum
Check it out. 📚
Learn CS major knowledge based on design patterns, networks, operating systems, databases, data structures, and past interview questions.
Chapter 0
Essential knowledge for developers
We provide detailed information on the basic knowledge developers need, such as JSON, API, XML, Docker, and containers, which are essential knowledge for developers and basic knowledge questions that frequently come up in interviews.
Chapter 1
Design Pattern
Libraries and frameworks tend to include design patterns as a basic feature. That's why, in interviews, they sometimes ask about design patterns as if they know the library well. They tell you not only the concept of design patterns, but also how they are actually included in the library.
Chapter 2
network
It provides information on important IPs, HTTPs, REST APIs, etc. in the network, and how to solve large-scale traffic that frequently comes up as a follow-up question. It goes into the important parts in depth and explains only the key points of the unimportant parts.
Chapter 3
Operating system
It provides an overview of the operating system, detailing processes, system calls, kernel, memory structures, etc.
Chapter 4
Database
Starting with entities, which are the basics of a database, we will focus on important parts of a database, such as transactions, indexing, isolation, normalization, and deadlocks in a database.
Chapter 5
Data Structure
First, we will learn the basics of data structures by explaining time complexity and space complexity, and then cover all the essential data structures such as queues and stacks.
Chapter 6
Interview know-how
If you have covered CS interviews so far, I will provide you with know-how based on my actual experience in personality and technical interviews and the "model answers" I gave during interviews.

Knowledge Sharer Interview 💬
Q. Is there anyone you would recommend this course to?
I would like to recommend this to those who have some programming experience and are now preparing for an interview at their desired company but don't know what to prepare for, as well as those who are non-majors or majors and want to acquire solid CS knowledge.
Q. Can I prepare for all CS interviews with this course?
Yes, it is possible. First, most of the content of this lecture is based on concepts from CS interview questions. In other words, it is a lecture prepared based on questions from actual IT majors. Second, I think it is more solid because the concepts are prepared based on my experience as well as the interview experiences of my developer friends. Third, I prepare not only for concepts from previous exams but also for core concepts of CS knowledge that are likely to appear. And furthermore, if students need these concepts, I review them and produce them to prepare for the "latest questions." That is why I think you can prepare for CS interviews with just this one lecture.
Q. How many days will it take to respond to my question?
You can expect a response within an hour, but usually it takes 1 to 3 days (excluding weekends and public holidays).
Q. What is the best way to study for this course?
Well.. Actually, I would like you to study with a strategy of memorizing all the contents of this lecture. Because this lecture prepares the general and core contents of CS + in-depth knowledge + interview questions, I think you will be able to perfectly prepare for the CS interview if you memorize all the contents of this lecture. That is why you should study slowly. I think it is best to study by watching the lecture for about 30 minutes to 1 hour a day, understanding and memorizing it, and setting aside about 2 months to study step by step.
Q. It seems like the training is mainly focused on Java or JavaScript, but I mainly work with Go and Python. Will I be able to understand it?
Yes, I understand. If you know at least one language, I've prepared a code that you can understand and that's about the same level of difficulty.

7% enrolledI deeply agree with all the points that other people have made in their long reviews, and they are critical for beginners learning CS. I regret buying it without reading the reviews in advance. Those who already know all the contents of the table of contents may find it useful for review, but considering the price, I don't think it's necessary to buy it and do that. If you're just learning it for the first time, just buy the book.
This review seems to be the most accurate. This is a lecture that can be covered sufficiently with a book.

36% enrolledAs a non-major, I had no knowledge of CS at all, so I always had a lot of worries about technical interviews. In the lecture, the instructor explained it in a much easier way by showing pictures or examples in the network part through a browser. I am filling in the gaps by repeating the instructor's book and lectures. Thank you for the great lecture book!

13% enrolledSince the overall CS knowledge is reviewed quickly and in depth, I can supplement the content without being too excessive or lacking. The tone and materials used for explanation are also good. I bought it before the interview and only took the parts I didn't remember well and had the interview, but I think I did well thanks to the interview. The lecture content is also continuously updated, so it seems like a good lecture to watch over and over again :)
