I applied in-person. The process took 6 months. I interviewed at Brigham and Women's Hospital (Boston, MA) in Feb 2013
Interview
Very formal and organized interview process. I gave a presentation first and then got a chance to talk with everyone in the lab for about 20 mins. Finally, someone in the lab showed me the lab general situations. I think the main part of the interview is talking with the PI and demonstrate your research.
Interview questions [1]
Question 1
What's your plan for future? How long can you stay? How can you deal with difficulties in the life and research? What kind of research skills do you have? How about your family?
