Korean job postings grow longer, more detailed in AI era: JobKorea

A recent analysis by JobKorea, a job portal operated by Worxphere, reveals that job postings in Korea have become significantly longer and more detailed in response to the growing influence of artificial intelligence (AI). The study, which examined job postings from 2021 to the third quarter of 2023, found a notable shift in the way companies present their requirements.

The share of postings including a dedicated section on preferred qualifications nearly doubled, rising from 14.5% in 2021 to 28.3% in 2023. Similarly, the number of postings listing required qualifications increased from 18.6% to 27.3% over the same period. This trend suggests that companies are becoming more specific in their expectations of potential employees.

Interestingly, since 2022, preferred qualifications have appeared more frequently than required qualifications. This shift indicates that companies may be prioritizing candidates who possess the desired skills, even if they are not strictly necessary for the job.

In addition to the increased focus on qualifications, job postings have also grown longer. The median length of postings rose by 79%, from 483 Korean characters (including spaces) in 2021 to 864 characters in 2023. The average length increased by 32%, from 817 characters to 1,077 characters. This suggests that companies are providing more comprehensive information about the roles they are offering, likely to ensure they attract the right candidates in the competitive job market shaped by AI.
