I applied online. The process took 3 months. I interviewed at Edelman (Chicago, IL) in Jan 2017
Interview
I went to a mixer, about a month later I got an invitation to come to the Chicago office for a 30 minute in-person interview. It's you in the room with 2 other Edelman recruiters. Others called this a stress interview, where they typically ask you for a different answer than the one you gave or to expand on the one you gave.
