The interview was held online (I live outside of Jabodetabek). There were two sessions. In the first session, I was interviewed by the Project Supervisor, the CTO (korean) and the HR. General questions, mostly. The interview was held in English, but since I included Korean ability in my resume, I was also told to explain IT stuff in Korean.
The second interview was the same, but this time, it was the CEO who interviewed me.
Overall, it was fine.
