The interviewer I met with went through all of her questions very rapidly and placed a large emphasis on how we only had 20 minutes available for the interview whenever I gave an answer that required a bit more explanation (like when she asked three questions in a row before I even had the chance to respond to the first question).

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.
