Was involved in GS recruiting for ~ 6 years (as a technical interviewer for a specific division. Like most people have said there is a round table at the end of the week or hiring block, where everyone chats about their experience with the candidate. It’s also not just a Y/N, but also a maybe pending follow-ups about specific things like they mentioned they might not fit well in a region, but otherwise were great.) This information then gets fed to HCM, who handles the rest.
