It is an onsite interview. Students arrived at Baltimore in the first day. In the morning of the second day, professors gave speech about their research. In the afternoon, students are interviewed by several professors individually. In the evening, students have dinner with current PhD students. In the third day morning, students have brunch with faculty members and PhD students.

It went really great. Everyone was super nice and didn't ask harsh questions. It was enjoyable. Only focus on your previous research experiences. If you are not sure about the answers just be honest
