This strategy usually falls apart for two reasons:
1. Some people are really good talkers and some people are really bad talkers, especially in an interview setting. That said, all the software companies that people usually complain about do have part of the interview process dedicated to past experience, more the more senior you are.
2. It doesn't scale. To ask really pertinent questions that can trip up a good talker you usually need someone with a lot of experience. But you also don't want them to spend all day doing interviews. You need some type of interview that more junior employees can collect signal from.
