Interview with the director in person at the school. I was asked about my resume's skills and related courses. Ask about the research experience that I did during graduate and undergrad study.

Everything went smooth and the interviewers were professional enough to ask questions about me and had quick responses. It contained a phone call interview and an online interview. Maybe there should be more processes but I haven't got a chance to go through all of them. Anyway, they are really good at hiring.
