That is quite rich coming from Braintrust. The founder should spend less time doing press interviews and more time listening to feedback from his own community. I was from the outside intrigued by the unique way of working and signed up to learn more about it.
The thing that immediately jumped out is community members complaining about failing the initial screening without any feedback at all. This initial screening is apparently an AI interview. If the AI is so great, it should be trivial to get it to explain why it rejected interviewees. Unless it has serious shortcomings that would be risky to publicize.
Alternatively, this could be a sneaky way of collecting training data for the AI by preying on unsuspecting humans.
