In the late 90s, I worked at a place that would walk people out as soon as we'd reached a hard-no decision. As the first tech interviewer left the room, in the hallway, the second would ask some innocuous yes/no question. ("Hey, my car's at the shop; can you give me a ride over there later?") The answer to that question was whether or not to continue the interview slate [and was almost always "yeah, sure, no problem"]. If it was yes, go into the room and introduce yourself. If it was no, they'd walk off together to find the recruiter who would walk the candidate out. That place never stopped doing the practice, but other places I've worked (including the current) have decided against that pretty brutal candidate experience. (And, as you say, have also had a policy not to share any information about the candidate's performance until after submitting the write-up and recommendation from the interview.)
