★ IT Bestseller
Successful developers develop strategies, not specs.
Everything you need to know about developer employment, straight from the Kakao interviewer.

As an interviewer at Coupang and Kakao, the author witnessed countless instances of highly qualified and qualified applicants being rejected. After this experience, he decided to personally guide developers on the job search strategies they need.
Overseas engineers spend a lot of time developing their interview skills and are relatively adept at finding and changing jobs.
In contrast, seeing that Korean developers are experiencing many difficulties, I decided to help.

Based on our experience of passing and failing countless applicants, we provide a detailed roadmap for developer employment, from resumes to career management.
It covers everything related to job hunting, from finding a company that's a good fit or a fast-growing gem to strategically structuring your portfolio, the real intentions behind interviewer questions, and essential practical concepts like high-volume processing and performance management.
Even if you don't get a job or change jobs right away, it will serve as a career guide for developers who want to continue growing.

The job market changed by AI,
The answer lies in job posting analysis and career management!

Building on the popular content from the first edition, this revised edition offers tips for preparing for a job market that has become more challenging due to the emergence of AI tools.
As the job market becomes increasingly narrow, more thorough job posting analysis is essential.
By training yourself to closely examine commonly overlooked job postings, you can understand exactly what companies are looking for and prepare accordingly.
For example, if a company prioritizes experience handling large-scale traffic, it can be inferred that the company is planning to transition to MSA and can make plans for it.


Moreover, in the AI ​​era, problem-solving skills will be valued more than simple coding skills.
To achieve this, we will learn about career management methods that are in line with trends, including self-development and interview preparation through the STAR technique, learning methods using AI tutoring, and work automation skills such as creating ERDs and sequence diagrams using AI tools.
