Very much discussion oriented, no excessively pointed or aggressive questions. Good back and forth with the interviewer. They do a good job of making the whole interview day pretty painless.

There wasn't really an interview process. They just look at your application, which does need to be very competitive. GRE scores, recommendation letters, GPA, and writing sample. Typical application. The recommendation letters and writing sample are probably the most important aspects of the whole process.

Applied to princeton graduate program online. Contacted by a professor for a skype interview. Answered questions about my previous research. No tough questions as I was prepared to talk about my resume.
