I applied online. The process took 2 weeks. I interviewed at Resonate (Reston, VA) in Sept 2011
Interview
There was one interview, with a written coding test. It only took 1 hour, with 2 random, computer science questions.
I was interviewed by 2 engineers and the VP of engineering, and was asked to whiteboard out solutions to the problems. Know your CS subjects well. As an employee/interviewer, we had a high rejection rate and were very selective of new candidates.

The questions are always different, so this won't help you.
