One interview with your chosen supervisor, depending on how your supervisor knows you but the question was mainly on how I wanted to conduct the research, and why that question was an important one to research

During the interview, I give a 5 min self-intro, 15 min past research and 15 min research plan. Then the professor asked me questions. The most important are: 1. why choosing his lab 2. do you know any Japanese? Living in tokyo without Japanese is not easy.
