What you will gain after the course

Understanding Core Concepts of Computer Architecture
The ability to explain things verbally in technical interviews
Practical Workbook PDF Preparing for Follow-up Questions

🥲 Have you ever had this experience in an interview?

1. Cases where responses confuse concepts

❓InterviewerWhat are the characteristics of object-oriented programming?
💬 Candidate The SOLID principles. First, S is..(omitted)...
The characteristics of object-oriented programming (abstraction, encapsulation, inheritance, polymorphism) and
object-oriented design principles (SOLID) are being confused.
This can give the impression that the foundational concepts are not solidly understood.

2. When you only know What, but can't explain How / Why

❓Interviewer What are the characteristics of TCP?
💬 Candidate It's a protocol that guarantees reliability.
❓ Interviewer What mechanisms guarantee reliability?
💬 Candidate Uh... well... it makes transmission safe... like...
You only know superficial definitions and are not prepared to explain the principles.
If the 3-way handshake, sequence numbers, ACK, retransmission, flow control, and congestion control
are not connected as a single flow, you will inevitably get stuck on follow-up questions.

3. When You're Stumped by Basic Questions

❓Interviewer What is HTTP?
💬 Candidate Um... it's for sending and receiving data on the web... something like that...?
It's a concept we're all too familiar with, but when we try to explain it in one sentence, the words don't come together.
This isn't a lack of knowledge, but rather a lack of experience in organizing and articulating it.

Just knowing is not enough. It only becomes true skill when you can articulate it.

1⃣ Interview-focused course with only the essentials

I've gathered and organized all the essential concepts and principles you must review before your interview
I've structured it to build fundamentals while ultimately serving as interview preparation material
Not just a simple summary, but structured with diagrams and easy explanations so that even non-majors can fully understand.
You can quickly organize the main content while understanding why it's important as you learn

2⃣ Appendix [Interview Practice] Included

In interviews, the ability to explain things clearly is far more important than simply knowing them
However, organizing and practicing on your own is not easy and can be a tedious task
At the end of the lecture materials, we include "Answer in One or Two Sentences" training to reduce the effort of summarizing.

3⃣ Prepare for follow-up questions withTechnical Interview Practice Workbook PDFprovided

"Will this course alone really be enough for speaking practice?"
After much consideration,
I created a technical interview practice workbook.
You can practice speaking as if in a real interview even by yourself.
You can find detailed information about the workbook structure and how to use it in the workbook introduction video at the beginning of the course.

4⃣ A course that keeps growing with a single purchase

This course is provided with unlimited access period
New explanations, additional examples, and other content will continue to be expanded.
Even if the price increases as content is added, students who have already purchased
can access all content without additional cost
Whenever you need it, you can come back and keep referring to this CS fundamentals book

1⃣ Download the materials and learn key concepts while watching the lectures.
2⃣ Take notes on important parts to create your own CS interview notes.
3⃣ Save them on your phone and review briefly whenever you have time.

If you have an interview coming up,
and don't have much time → Use the appendix [Interview Practice] in the course materials to quickly sharpen your interview skills.
If you have time → Complete your speaking practice like a real interview with the Technical Interview Practice Workbook.

⭐️⭐️⭐️⭐️⭐️

1. A course that shows how much the instructor has thought and considered from the student's perspective (seems to consider the learner's flow of understanding)
2. Easy to understand with diverse visual materials and examples
3. When learning knowledge, it mentions and reminds you of previously learned content, connecting the knowledge. Knowledge connects and the big picture emerges.
4. The depth of knowledge is not shallow. I'm taking the OS course right after the computer architecture course, and the synergy is great.
5. Scratches all the itches about "why" & "why we use this".
ps. Sorry to the instructor, but... this is a course I want to keep to myself.

- 'Operating Systems' Course Review

⭐️⭐️⭐️⭐️⭐️

Despite the short lecture duration, I really appreciate how you clearly explain only the important parts. I thought it would be mostly theoretical lectures and wouldn't cover SQL queries, but it was great that you showed examples one by one while teaching basic syntax and how to write queries. After that, the coverage of joins, normalization, transactions, indexes and data optimization, and security was excellent, and although I haven't tried other paid courses yet, the last lecture appendix titled "Interview Practice" was great for self-study and practice as it directly showed questions and answers. The lecture duration isn't too long if you focus, so I think I'll go through it multiple times. Thank you

- 'Database' Course Reviews

🖐 Hello! Let me introduce myself! 🙇

As a non-major, when I first prepared for my developer job search, I focused solely on algorithms and coding tests.
I gained some confidence and passed most coding tests, but I kept failing at the next hurdle—technical interviews. What was the problem? It was the lack of CS (Computer Science) knowledge.

I understand the thirst for fundamentals (CS knowledge, programming languages, etc.) better than anyone. I've dug through countless materials through self-study and built my own know-how, and now I'm working as a 🧑🏻‍💻 Kakao developer.

Since childhood, I've been more confident than anyone in combining and reorganizing various materials to create 'my own consolidated notes.' This course is precisely that secret notebook containing all those know-hows and passion.
