> for the same reason we don't offer take home interview assignments: it's biased against people who don't have a whole lot of extra time at home.

This is just another single dimension hiring credential, that will result in limiting your hiring pool to people like yourself. My code ran on 70+ million machines last month, but I've come to decline any timed or proctored technical interviews.

It's not that I'm too good for whiteboarding or timed tests, or that my options are so open that there isn't significant cost in doing so - quite the opposite: I'm come to find the process so traumatic that going through with it isn't worth it for anyone involved: those jobs just aren't open to people like me.
