What you will gain after the course

Understanding Core Concepts of Data Structures
The ability to explain verbally in technical interviews
Practical Workbook PDF That Prepares You for Follow-up Questions

🥲 Have you ever had this experience in an interview?

1. Confusing concepts when answering

❓InterviewerWhat are the characteristics of object-oriented programming?
💬 Candidate The SOLID principles. First, S is..(omitted)...
This is a situation where the characteristics of object-oriented programming (abstraction, encapsulation, inheritance, polymorphism) and
object-oriented design principles (SOLID) are confused.
This can give the impression that the fundamental conceptual framework is not established.

2. Knowing only What, but unable to 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 secure... like...
You only know the superficial definition and are not prepared to explain the underlying 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. Getting stuck on basic questions

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

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

1⃣ CS Notes organized specifically for interview preparation

We've compiled essential concepts and principles you must review before interviews into comprehensive lecture materials.
While building your fundamentals, it's structured so you can review it again right before your interview.
It's not just a simple summary, but includes diagrams and easy explanations so that even non-majors can fully understand.

Computer Architecture Lecture Material Example

2⃣ Appendix | Interview Practice Materials Provided

In interviews, the ability to explain clearly is far more important than simply knowing something.
However, organizing and practicing on your own is not easy and can be a tedious task.
At the end of the lecture materials, we've included "answering in one or two sentences" training to reduce the effort of organizing.

Database Course Appendix Example

3⃣ Prepare for follow-up questions with our Technical Interview Practice Workbook PDFincluded

"Will this course alone really be enough for speaking practice?"
After much consideration,
I created a Technical Interview Practice Workbook.
Designed so you can practice speaking as if in a real interview on your own.
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.

Operating System Workbook Example

4⃣ A course that keeps growing with a one-time purchase

This course is provided with unlimited access.
The content will continue to expand with new explanations, additional examples, and more.
Even if the price increases as content is added, students who have already purchased
can access all content at no additional cost.
It's a CS fundamentals textbook you can keep coming back to whenever you need it.

1⃣ Download the materials and learn key concepts while watching the lectures.
2⃣ Take notes on important parts to create your own CS interview notebook.
3⃣ Save it 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 author 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, mentions and recalls previously learned content to connect knowledge. Knowledge connects and the big picture emerges.
4. The depth of knowledge is not shallow. Currently taking OS right after Computer Architecture, and the synergy is great.
5. Scratches all the itches about "why" & "why it's used".
ps. Sorry to the author 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. Since it was somewhat theory-focused, I didn't expect SQL queries to be covered, 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. I haven't tried other paid courses yet, but the last lecture appendix titled "Interview Practice" showed actual questions and answers, which was great for self-study and practice. The lecture duration isn't too long if you focus, so I think I'll go through it multiple times. Thank you

-'Database' Course Review

🖐 Hello! Let me introduce myself! 🙇

As someone from a non-CS background, when I first prepared for a developer job, I only focused 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 know the thirst for fundamentals (CS knowledge, programming languages, etc.) better than anyone. I dug into countless materials through self-study and built my own know-how, and now I'm working as a 🧑🏻‍💻 Kakao developer.

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

Data Structure Overview
- Data structure classification, time complexity and space complexity
Arrays and Lists
- Advantages and disadvantages of arrays, advantages and disadvantages of lists, various types of lists
Stack and Queue
- Stack, Queue, Deque
Hash Table
- Hash functions, collision resolution methods for hash functions
Graph
- Types of graphs, graph implementation, graph traversal (BFS, DFS)
Tree
- Types of trees, binary search tree, binary tree traversal, AVL tree, Trie data structure
Heap
- Heap operations, heap implementation and usage, priority queue
[Appendix] Interview Practice
- Review key concepts once more in Q&A format

Recommended for
these people

Who is this course right for?

Beginner developers who have tried coding but are confused about data structure concepts or lack confidence in them
Job seekers and career changers who want to quickly review data structure concepts before a technical interview
Someone who gets stuck on choosing the right data structure or implementation approach while solving algorithm problems
For those who find structures like trees, graphs, and heaps too complex

Need to know before starting?

It would be great if you have experience learning a programming language!
