Always trust and watch instructor Park Jae-sung! Thank you for providing such a great lecture. I had never received professional resume coaching before, so I was often unsure of what to focus on when writing one, which was a shame. However, this lecture helped me identify my problems and set a direction, making it a truly beneficial experience. Despite being an experienced job applicant, I was able to gain a lot of valuable insights. Thank you once again!

That is, I was able to learn how even non-majors can effectively appeal to their strengths while listening to the lecture. I realized that it is not just about listing technical stacks, but how to organize project experiences and how to structure a portfolio in the way that companies want.

Before watching this lecture, I thought that when doing a project, it was just over once it was done, but after watching the lecture, I felt that it is important to proceed with the project while thinking about what to write in my resume and portfolio. I'm writing my resume for the first time, so I can't complete it perfectly, but I'll fix it little by little!

What you will gain after the course

  • 6 Absolute Rules for a Winning Resume

  • Characteristics of developers that interviewers want to hire

  • How to Write a Resume/Portfolio Draft

  • The actual resume review process conducted from an interviewer's perspective

  • Providing resume templates with structures that interviewers prefer


🏆 Real Resume/Portfolio Success Cases

** These are actual acceptance messages sent by my students while conducting 1:1 resume/portfolio consulting.


😭 6 Absolute Rules of Resumes That Get You Hired?!

I started development as a non-major and worked as CTO at various companies, and now I'm working as an educator. My name is Park Jae-sung.

I've been consistently providing 1:1 consulting to review and give feedback on resumes for about 2 years. Through that process, I reviewed and provided feedback on hundreds of job seekers' resumes and helped many students get hired. When I laid out all the resumes of the students I've helped get hired so far, surprisingly, there were 6 common characteristics as if they had made a pact.

'The Theory of Predetermined Answers, The Paradox of More is Better, The Curse of Abstract Words, Squid Game Theory, Mafia Game Theory, The 30-Second Rule'

Resumes that pass all follow these 6 principles well. If you know and apply just these 6 principles, your resume pass rate will significantly increase, and you'll be able to judge for yourself what parts of your resume are wrong and what areas need improvement. You'll also understand what interviewers are thinking when reviewing resumes, which resumes they pass and which ones they reject.

Many job seekers fail at the document screening stage, and when you look at why they fail, it's simply because they don't know how. Resumes/portfolios are absolutely not a matter of talent. It's just a difference between knowing and not knowing.

Learning to ride a bicycle feels difficult at first, but once you learn it just that one time, you never forget, right? Resumes and portfolios are exactly the same. Once you learn it just once, you'll never suffer over resumes or portfolios again.

I hope this course can serve as a guide for those who feel lost about how to create resumes and portfolios. I'll see you in the course.

✨ 4 Points I Focused on While Creating This Course

I analyzed actual resumes that passed and extracted 6 common characteristics that anyone can apply. Through these 6 principles, I structured the course so you can write a resume that will get you hired on your own.

I'll explain what mindset interviewers have when evaluating resumes. By learning the interviewer's perspective, you'll be able to judge for yourself how to write a resume to make it a good one.

So you can write your resume right away after completing the course, we provide a resume template with a structure that interviewers prefer. Use this resume template to quickly complete your resume.

We'll show you the process of providing feedback on 7 actual resume samples. It's designed so you can learn what interviewers think when reviewing resumes, which resumes get rejected, and which resumes catch their attention.

👍 This course is great for:

People who feel lost about how to write their resume

Those who want to increase their resume screening pass rate

Those who want to know the common traits of successful resumes

🙊 After completing this course?

You'll learn which resumes interviewers accept and which ones they reject. Not only that, but you'll also realize how to write resumes and portfolios that get accepted.

Reference Information

Even while writing your resume after watching this lecture, you may encounter moments where you feel stuck, or there may be times when what I've taught you doesn't quite make sense. And you might also feel anxious about whether it's okay to write it this way.

I went through the same thing when I was job hunting. I had countless worries about whether I was writing things correctly, or if the interviewer would dislike what I wrote. I understand that anxious feeling well, so whenever that happens, please feel free to ask using the Inflearn Q&A board or 1:1 chat.

I won't be able to review entire resumes due to time constraints, but I'll do my best to think through and answer any questions or concerns you have while writing your resume!

🚨 Make sure to check what kind of person is providing the education!

If you meet the wrong doctor, you could die from an untreated illness in that moment. But death ends with that moment of suffering. However, if you meet the wrong teacher and receive poor education, you will suffer throughout your entire life.

Due to wrong education, you may end up at an unwanted company, receive a smaller salary than expected, and suffer for the rest of your life because of it. Not only that, but the wrong education you received gets passed down to your children as well.

I believe that education can truly change a person's life in a positive way, but on the other hand, it can also completely ruin a person's life. That's how much I believe education carries a heavy responsibility.

Therefore, please check who is providing the education, what kind of person they are, what path they have walked, and make a careful judgment.

👋 Hello!
I'm finally introducing myself ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

Hello!

I started studying development as a non-major. Before I knew it, I've become a 6-year developer! Recently, I've been working as a developer while serving as CTO at 2 companies. Whenever I have time, I've been doing coding lectures, company development consulting, and speaking engagements.

The number of students I've taught has now surpassed 24,000 (as of July 2025)! Every time I teach my students, I feel it again—I can't forget the sense of fulfillment from education, so I plan to continue teaching consistently on Inflearn.
(* Among students, successful hires at Kakao Pay, Yanolja, and Woowa Brothers)

Just as I received a lot of help when I was going through difficult and challenging times, I wanted to become someone who could help many others. And I felt most proud and happy when the value I created through development had a positive impact on other people.

For these reasons, I hope that by sharing and giving what I've worked hard to achieve, those people can live a slightly better life.

Thank you!

    I learned about viewing applicants from the perspective of an interviewer. I also think these are great tips that can be applied not only to resumes and portfolios, but also to daily life! 1. Specific instructions -> Can be immediately applied to your resume 2. Easy explanations through analogies -> Goes beyond just remembering; it's imprinted in your mind

      Specific feedback on Seung-hwan's lecture is helpful to me too! Actually, it's good to look at a resume from the interviewer's perspective to accurately grasp the intention and key points :) I believe you'll finish your resume well based on what you've learned. Fighting! 👍👍

    I'm a student who recently chose to study backend development. Although I made the choice, I felt lost without a sense of direction, and the idea of creating a portfolio seemed vague. However, after taking this lecture, I feel like I have a clearer perspective. Thank you.

      Instructor

      jack0506, I see you've recently started backend development! It must feel unfamiliar and difficult since it's all new, but I'm relieved to see you're already getting the hang of it by watching the lectures ☺️ If you keep putting in the effort, you'll gradually start to see things more clearly~! 👍

    The combination of theory and concrete examples makes it easy to understand and apply. However, it's a shame there aren't any examples of front-end resumes.

      You worked hard to complete the entire course, Namsoo! If possible, I'll try to add a front-end resume to the next course update :D I hope you apply the theories I explained well and get good results in the job market 😊😊

    My mind was blown by a story different from what I had known all along. If I had seen this lecture a year ago, I would have already gotten a job 😆😆... I'm glad that I can at least set the right direction now. Thank you for the great lectures every time!
