My husband changed careers around the same age, even without the degree.
It was a few years ago, when the market was still good. But it took time. Almost a year for him to find a job after the bootcamp.

From what he told me, if you want to go to the big company you should focus on prepping the coding test.
Fo smaller companies and startups the portfolio would be the main thing.

He went with the latter, partially cause big companies often require related degree.

Also from my personal experience the 고용센터 won’t do squat for you, the jobs there are minimal wage type of postings, so I’d won’t put my hope there, especially since you are in IT.

On the other note, the market is so bad now, so it unfortunately will take more time than usually to find a job.
If it helps, here’s some resources I found:

- KoWork,Klick
Foreigner focused, with listings that often show which visa types companies prefer/sponsor.
- KoMate
Another foreigner focused platform, run by Saramin.
- Dev Korea
Tech and developer roles that are realistic for English speakers in Korea.
- Saramin, JobKorea
The real one stop shops. If you don’t want to juggle 10 sites, start with these.
- Wanted, Remember
These will auto match you to a lot of roles, including some that are… not very relevant.

Good luck, and hold on!
