Q: How common is it for a faculty/school to request/demand the good PhD applicants to come in for an interview?
For someone that lives outside of the U.S. and wants to apply to do a doctorate in the U.S., should that person temporarily relocate to the U.S. (at the correct time and for the correct duration of course) with the expectation that they'll have to interview in order to get in?
Do top schools vary from mid-ranked schools when it comes to interview frequency? Does it vary by faculty?
