I see, yes, stereotyping based on some perceived “flaw” like accent is absolutely wrong and needs anti-bias training to remedy. It is tough though. I want people I interview for my company and team to get along with everyone, and trying to make that evaluation in a short amount of time can often result in immense bias. In the end, interviewing is fucking hard.

No question. Personally I think the first and most important step is getting everyone in our industry to admit that they have deeply internalized biases that they're not likely to be fully aware of and that they have a real effect on important decisions. Once you've acknowledged that you can start to check yourself.

Agreed, and it's up to the organization to remedy those biases with multiple rounds of interviews, and most importantly, making sure those multiple rounds consist of interviewers with different inherent biases and tendencies.
