Completely blind interviews by interactive text chat session only are the closet thing to fair I can conceive; possibly with a shared blackboard or big screen of somekind on provided interview hardware.
Surely there's a better way of acknowledging and mitigating harmful stereotypes?
If that went well then you'd have a "real" second/final interview. The system was designed to remove some of the bias from the process, and seemed to work well for that.
I know it crossed my mind that multiple people could be sharing a keyboard during the blind-sessions.
I struggle with the opposite in Europe. (Many) Less progressive companies still ask for CVs with date of birth and photograph.
Even if they're fine with "blind" CVs, the first interview will invariably be just a 15min video call with someone from HR who doesn't know the first thing about the position, and is just there to look at your face and listen to you reiterate your CV.
(I've worked in the UK for most of my life, but I've been located in Finland for the past five years, or so.)
It's also not often specified explicitly - I notably recently saw the first job offer stating "we consider a complete application to include DOB and photograph".
It has, however, come up every single time when talking to third party recruiters. Maybe they carry additional bias.
I have access to the name when I'm reviewing the code, but I specifically don't look at it until afterwards. I'm sure it wouldn't make a difference, but I figure there's no harm in doing it that way, so why not?
Making it obviously impossible for the judges to pick up the signals on which to discriminate, if it can be done, is much better.
