Initial phone screening, then interview with talent acquisition, then language test, then interview with mid level team member and then interview with a senior member of the team. That is the final stage.

I only attended the first interview. The HR manager was neither friendly nor unfriendly. It was just a normal screening interview. Only self-introduction and motivation for application were conducted in English, and the rest were conducted in Korean. The HR manager asked questions focusing on my background and history rather than understanding the job itself.
