This is a practical technical interview strategy lecture shared directly by a Technical Director who has conducted over N,000 technical interviews. There is no such thing as a "guaranteed way to pass" or a "guaranteed formula for success" in this world. I will show you the interviewer's perspective—how they perceive a resume during the preparation stage, and what they focus on and prioritize during the interview process. A technical interview is not a memorization subject with fixed answers. The core of this lecture is understanding the essence of the process itself: showing your true self to the interviewer and persuading them. Whether you are an experienced professional or a newcomer, this lecture will be helpful for any developer who has ever worried about technical interviews.

Messy code, a flood of requirements... If you're looking for a breakthrough with AI, Learn how to become a "high-performing developer" by leveraging AI in legacy environments, taught by the former VP of Engineering at Toss Payments. Legacy code isn't going anywhere, even in the age of AI. It’s no exaggeration to say that every company has legacy code, unless they were founded today. So, how should we utilize AI in this reality? In this course, the former VP of Engineering at Toss Payments, who led a large-scale payment service organization, demonstrates firsthand how to work effectively using AI in legacy environments. This isn't just a course about how to use AI or basic coding skills. The goal is to help you develop your "critical thinking" as a developer and truly understand what it means to work effectively.

This course focuses on building the real skills needed in actual development work. The goal is not simply to learn how to write code well, but to experience how to work well as a developer. The examples are based on the commerce domain, covering cases frequently encountered in real-world work environments, and are provided in SpringBoot & Kotlin. However, it's a course where anyone can contemplate and experience real-world development through thought-provoking content, without being dependent on any specific language or framework. Based on the practical perspective of a senior developer and former director at Toss Payments who led a large-scale payment service organization, the course is designed to help you learn the thought processes and design decisions used in actual work environments.

Because you never know when or how software will grow, you always need to be prepared to continue growing. This provides one direction for that.
