I really wish I had the reference, but I did the "paid trial" for a week for out interviewing process (startup, 40m evaluation) based on an article that said that standard tech interviews gave you an 18% predictability and that paid trials gave you about 72% (it was only one study).
I can tell you that at our company we definitely dodged candidates here and I was very happy with everyone we hired (but you could call that bias, as I was the hiring manager -- but I also worked withe veryone I hired)
