I applied through a recruiter. The process took 1 week. I interviewed at Red Hat (Raleigh, NC) in Sept 2012
Interview
I found the Red Hat interview process to be to-the-point, well organized, and appropriate in terms of questions. The fact that it is such a group-minded environment came through clearly in the interview methods to include a great degree of participation from the peers.
