We are using Vapi AI Phone calls to conduct pre-screening interviews with candidates we are interested in hiring. The average interview lasts 10 minutes. However, during these calls, the AI frequently interrupts candidates, causing them to feel stressed and hesitant to continue speaking. Even when they persist, the AI cuts them off to summarize their statements. This is not the experience we desire; we expect the AI to listen attentively without interrupting. We have tried adjusting the 'Smart' feature by increasing the waiting time to its maximum, but this has not resolved the issue. Could you please suggest further steps to improve this experience?
