I originally got a call from a recruiter who had seen my resume online, who spent ~20 minutes screening me for the in-person round. The in-person interview was a bit of a 'cattle call' - there were ~10 other people interviewing the same day. They put each of us in separate interview rooms, and had 3 employees cycle in for 30 minute interviews. Most questions were "tell me about yourself / your experience" type questions. It was extremely efficient, but pretty impersonal because there was no guarantee that you were interviewing with people you would work actually work with.
