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

I'm Park Jaesung, who started development as a non-major and worked as CTO at various companies, and am currently active as an educator.

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

'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'

All the resumes that passed followed these 6 principles well. If you just know and apply these 6 principles, your document screening pass rate will dramatically increase, and you'll be able to judge for yourself what parts of your resume are wrong and where you need to make improvements. You'll also understand what interviewers are thinking when they review resumes, which resumes they pass and which ones they reject.

Many job seekers get rejected during the document screening stage, and when you look at the reasons for rejection, it's simply because they don't know the method. Resumes/portfolios are absolutely not a matter of talent. It's just a difference between knowing and not knowing.

Learning to ride a bicycle also feels difficult at first, but once you learn it just once, you never forget it, right? Resumes and portfolios are exactly the same. Once you learn it properly just once, you won't suffer from resumes or portfolios anymore.

I hope this course can serve as a guide for those who are struggling with how to create resumes or portfolios. I'll see you in the course.

✨ 4 Points I Focused on While Creating the Course

👍 Great for these types of people!

✔ Reference Notes

After watching this lecture and working on your resume, you might find yourself stuck at various points, or there might be moments when the content I've shared doesn't quite make sense to you. And you might also feel anxious about whether you're writing it correctly.

I was the same way when I was job hunting. I had countless worries about whether I was writing things correctly, whether writing like this would make the interviewer dislike me. I understand that anxious feeling well, so whenever you feel that way, please use the Inflearn Q&A board or 1:1 chat room to ask questions.

Due to time constraints, I won't be able to review your entire resume, 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 might face death because your illness can't be cured at that moment. But death ends with the pain of that moment. However, if you meet the wrong teacher and receive poor education, you will suffer throughout your entire life.

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

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 why I believe education carries such heavy responsibility.

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

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

Hello!

I started studying development as someone from a non-technical background. Before I knew it, I've already become a 6-year veteran developer! Recently, I've been working as a developer while serving as CTO at two companies. Whenever I have spare time, I've been doing coding lectures, company development consulting, and giving talks.

The number of students I've taught has now exceeded 24,000 (as of July 2025)! Every time I teach various students, I always feel the same way - I can't forget the sense of pride in education, so I plan to continue providing education consistently on Inflearn.
(* Among students, successful candidates for Kakao Pay, Yanolja, and Woowa Brothers have been produced)

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

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

Thank you!
