Job Interview with Virtual Recruiter

I am the founder of a startup. We're making AI solutions for enterprise customers. We are currently working on a product for candidates. This is a virtual assistant that can interview the candidates, answer their questions, tell about the company, the team and much more. The interview takes place through video via a browser or mobile app. The candidate can practice before the interview, pass a test interview. As a result, they will receive feedback from the assistant: which questions they answered correctly and which did not; the analytic report of their speech; where they had long pauses; the moments when they looked confident and in opposite quite shy, etc. We are using different machine learning algorithms for doing it well. What do you think? Does this kind of tool look useful for you?
