你对那所学校什么问题感兴趣就直接问他什么问题。一般而言，国际学生比较关心的问题有：
1） How soon can I get the result after this interview please?
2) Does your school provide students with many on-campus employment opportunities?
3) What kind of career opportunities/service does your school provide?
问的比较切合实际会让他觉得you're serious about your education and career after that.
