Is it possible to study Korean and do an internship in Seoul on a working holiday?

Hello. I will soon be going to Korea on a working holiday visa and I am looking for various ways to learn Korean. In the process, I came across a place called Lexis Korea. This place has a lot of good reviews overall, and they also offer a 'work-study program' specifically for working holiday students. I heard that this program provides an opportunity to study Korean and at the same time, offers internship opportunities to gain practical work experience in Korea. However, I have not been able to find specific information or reviews about this program yet, so I have many questions. Is there anyone who has experienced this program? If you have, I am curious about how it was. Thank you!
