Given that a lot of you do not have impact on hiring decisions I'd sign your face to face point, despite me not understanding the benefit of seeing if someone actually has the expertise, as most likely you also wont be able to unhire them.
Can't we solve this by just having on-site interviews?
I guess my hope with the face to face is that people take the feedback and learn to do the actual work again. Right now it feels like a lot of this kind of collaboration and what is okay and what no has to be figured out.
