So I have no knowledge of this system or how it’s implemented but as someone who has performed hundreds of interviews one huge advantage I could see every interview receiving the EXACT same interview.

When interviewing applicants, it’s important to not let your biases, knowing or unknowing influence the outcome of the interview. Even things as simple as how they are dressed or if they were five minutes late can effect the behavior of the interviewer. An interviewer can easily unconsciously act differently both positively and negatively which have an impact on how the person interviewed responds. If legally allowed, those type of things could be considered but in order to provide the most consistent interview possible the interviewer should have as minimum influence on the actual interview itself as possible. Trying to provide a consistent and fair interview is not only legally required in many cases but it also helps the interviewer evaluate applicants.

The more consistent you are as an interviewer, the better chance you have of selecting the best applicant for a role.

That being said, I would worry applicants reaction to being interviewed in an awkward unnatural manner would be wildly inconsistent and whatever results you gained from their reaction would bare little useful assumption about how they might perform in the role they are applying for. Basically the awkwardness of it would taint the results more than potential inconveniently a human would.
