I ask this out of genuine curiosity and not to try to start an argument: could you help point us towards this research? This point frequently comes up when discussing interviews, but I've never seen references to specific research and I don't know where to even start looking.
I don't know - my HR department tells me our process is research backed, but not how to verify their claim. I doubt they are lying. However I honestly don't know how to search academic literature to find it. I suppose I should ask HR someday, or you could ask your HR rep.
My previous employer was about 1k engineers and elements of the interview process were research-backed, but it was mostly procedural (order of rounds, length of interviews, etc) and based on internal data. But I now work at a startup where we make a best effort based on everyone's previous experiences.
