Any reason not to spam mock interviews with ChatGPT voice?

Thinking of providing my entire app + some context secondaries to ChatGPt to spam mock interviews. Immediate feedback about framing and exhaustively sampling random interview questions seems helpful. Of course, supplemented with self-recordings to refine cadence, fillers etc. but how would ChatGPT hold up early on in interview prep to just get an idea of what I want to communicate/who I want to communicate myself as?

Thoughts?
