您好，感谢您关注楷维留学指南，您的问题回答如下：hub面试是一种校外面试，一般是美国大学的面试官在校园外的某个地方举办面试，然后，面试者都去那个地方参加面试。

　　Normally, in a hub interview, an interviewer stays in an off campus interview room and interviewee come in one by one according to appointment. It is more of an off-campus admissions face to face interview. The interview is often from the admissions, sometimes admissions director.

　　The "HUB" is the place the interviewer stays.

　　Schools such Wharton often hold Hub interview in big cities such as Beijing/Shanghai/Hong Kong.
