SUNY AMS(OR Track) PhD Interview 求指教

今天查邮件发现来了面试通知，具体正文如下：

Thanks for your interests in our OR PhD programs. Now you are on our final list, and we’d like to proceed with an interview over Skype/Hangout to discuss next steps. Could you please let me know your availability during the next week (please take the time difference into consideration)?

请问这个是学术面还是流程面？各位大牛学长学姐们有什么经验么？看地里原来都是北京线下面，感觉有点儿慌。本来还打算下周在香港玩的，看来得提早回去了。
