I applied online. The process took 4 months. I interviewed at Columbia University (New York, NY)
Interview
Application to the PhD program is standard. Three letters of recommendation are probably the most important, followed by research experience, then grades and reputation of undergraduate institution. There's also a personal statement and GRE scores.
