It explains the brief flow of how to write a resume and create a strategy from the perspective of a senior interviewer. I was holding on to my mental state even though I had been rejected in consecutive job applications as a career candidate recently, and I was reorganizing my resume and career skills, but you provided me with a point to think about again, so I will get up and try again.

It was very helpful because you explained it in a simple yet systematic way. While I'm not sure if it will lead to success when applied to my actual resume, I feel like my cluttered thoughts have been organized.

Instructor Introduction

  • I am a senior developer with 20 years of experience in Java, Spring, and MSA-based development. Having served as an interviewer at Coupang, LG Fashion, Kakao, and other companies for several years, I would like to share my experiences from document screening and technical interviews.

  • I have witnessed many candidates with good backgrounds and skills face rejection in interviews, which led me to contemplate how I could help them. This inspired me to publish a book in 2024 titled [Developer Technical Interview Notes, Hanbit Media], which contains guidance for preparing in the right direction.

  • As a senior who had the same concerns about job hunting and career transitions, and as a developer who went through many trials and errors to develop my lacking career, I aimed to present a clear roadmap.

        The portfolio composition and application methods were systematically organized from a 'practical perspective'. The emphasis on the structure for organizing resumes was practical, and you provided detailed guidance on how to efficiently write job posting analysis and application documents that create an at-a-glance career overview. It seems like this became an opportunity to review my resume once more.
