I applied in-person. The process took 1 day. I interviewed at Caltech (California)
Interview
Full Day 9am - 9pm. I had a meeting with the primary faculty and then meetings with the subdivisions of the research group. Several senior faculty and a postdoc took me to lunch and then I gave a 50 min presentation of my doctoral research. Afterwards, I met with more group members until the middle of the afternoon and then had an exit interview with the primary faculty. That evening, I attended a group social function.
