This course was created to solve a common problem many people face while preparing for developer jobs: "I studied CS and data structures, but I get tongue-tied during interviews." While conducting actual interviews at companies like Naver, Kakao, and Toss, I noticed that most candidates have memorized concepts but cannot explain why those concepts are necessary or how they are applied in real-world situations. Rather than simple rote memorization, this course teaches you how to understand the interviewer's intent and provide more persuasive answers to the same questions. Whether it's the OSI 7 layers, data structures, or coding tests, we focus on why you need to know them, when they are used, and how to speak about them to receive a positive evaluation in an interview. This course is for those who want to become developers who can explain what they understand in their own words, rather than just giving the same answers as everyone else.

Listening to the interview speech can help you pass the interview with flying colors.

Many developers say they have learned object-oriented programming. However, in reality, most only know the "syntax" of classes, inheritance, and polymorphism. This lecture is not a syntax explanation. ✔ Why did object-oriented programming emerge? ✔ What is an object, and why is 'responsibility' important? ✔ Why does polymorphism create scalable structures? ✔ How does object-oriented programming connect to computer science? I will summarize the "real object-oriented thinking" I felt while personally experiencing system design in just 30 minutes. Through this lecture, you will come to understand object-oriented programming not as a 'coding style,' but as a 'design strategy for controlling complexity.'

This course does not teach fashion. It structurally interprets how retail works. Sales are not merely the result of selling; they are the outcome of a system where KPI design, goal management, inventory turnover, workforce operations, and the strategic gap between headquarters and the field are all interconnected. Stagnant sales and organizational conflicts are not issues of emotion, but issues of design. Through the interpretation of sales structures, the principles of KPI operation, the design of operational frameworks, and the analysis of strategic conflicts, this course redefines retail from the perspective of data and structure. It is a process of moving beyond simply understanding retail to gaining the vision to design it.
