Yes @Amin VZ this is a good use case for a strict state-driven flow, not open conversation. With VAPI, you should explicitly anchor the interview to a fixed question list and force the model to only operate on “current question → capture answer → move to next”. The key improvement is making the question index deterministic (either via VAPI session state or reinforced in the prompt), so it never has to guess what comes next. I can help you structure a clean system prompt + flow logic that reliably holds 30 questions without losing sequence or drifting.
