I'm Ande, and I prepared this lecture with Hong as a Naver interviewer. In an interview, well... these kinds of questions can be asked, but realistically, there are many more diverse and rich questions. It also varies depending on whether you are an experienced professional or a newcomer. However, regardless of the question, the important part you should focus on is not just being someone who answers the interviewer's question, but how you interpret that question and what values you use to explain your answer. It's okay if your answer to a question is incorrect. However, saying something like, "I knew about this part and wanted to improve it, so I used it this way," feels much more impactful in an interview. Please don't just memorize theories. If you can explain how you interpret the concepts you know and how you applied them, I believe you will become a great developer.
