I applied online. The process took 2 months. I interviewed at Autodesk (New York, NY) in Mar 2014
Interview
Online application, phone interview, skype interview if not near the office, in office if closer. It wasn't anything above ordinary, but it was a long process. This was to be expected of a larger company so it didn't bother me, especially given the quality of the internship in the end.
