I applied through a recruiter. The process took 1+ week. I interviewed at Velir Studios (Somerville, MA) in Nov 2012
Interview
I had a 1 hour phone interview with a Lead Solutions Architect, which was fairly easy. This was followed by a 1 hour in-person interview with the same guy, and another Senior Solutions Architect. I received a notice that they'd like to make me an offer through the recruiter the next day.
