I applied online. The process took 1 day. I interviewed at NYU (New York University) (New York, NY) in Feb 2011
Interview
Had good time talking to the group and the supervisor. Typical interview as any other postdoc positions. The outcoming depends mostly on the chemistry between yourself and the supervisor. For postdocs, your resume mostly determines if you'll get the job even before you go in for on-site interview to meet and talk to the people.
