Yeah, the focus on the specific interview in the moment has both upsides and downsides. It can be frustrating and arbitrary but it also avoids some traditional in-group shenanigans and unfairness that is common in a lot of places. "I have to study all this crap even though I've done X, Y, and Z already" on one hand; "I can study independently and prepare for this interview even though I don't currently work at Google" on the other.

That said: names still help - if someone's on the fence then saying something like "they didn't do that great but based on their projects at Google I think they probably just had a bad day" isn't uncommon - but it's far from a requirement, which is a good thing.
