I don't know where you live, but at least in EU the cost of hiring the wrong person is monstrous. Unless they were literally caught stealing and you can fire them for gross negligance, you are looking at months of "performance improvement plans", when both of you know that it won't actually improve anything. All while you are paying them full salary, national insurance, tax etc, and also sinking in the time of another employee who now has to deal with the situation. It's extremely critical to not hire those people in the first place, and I would not trust an algorithm to do that.
