My brother has just finished a masters programme and is starting to apply for jobs, he's coming up against a lot of these.
He's smart, motivated, very hard working, and has the necessary credentials on his CV, but when talking to him he's quite monotone and low energy. Because of this, he's failing these automated video interviews as he looks like he's not a "team player" or "personable".
While interviewing practice is becoming more aware of bias against things like this, the training data for these "AI" systems are going to be based on those interviews conducted in the past, often with questionable outcomes. The software is sold as helping "remove bias", but it instead pulls interview bias forwards in more extreme ways to the CV-review stage, preventing candidates from ever getting in front of a human.
While multiple humans on a hiring team may overcome some of their biases working together, a single piece of software trained to look for stereotypes will exacerbate those biases.
