In any case, congratulations - first point, you've made it this far despite stuttering badly in previous interviews - they won't think you're any less good if you speak in person in front of them and stutter. They see your potential and your performance, it doesn't make your effort less valuable just because of the pronunciation. Keep that in mind, maybe it will take away some of your fear or excitement. I'm incredibly proud of you for still getting through it until now - you deserve it. A lot is the inner attitude. Keep your motivation for the topic and just talk at it, fuck it no matter how many times you stutter, take a breath and move on. Otherwise, I could recommend that you get a really good night's sleep over the next few days and do all the routines that will give you a good morning/day, for example. I'm keeping my fingers crossed for you, you can do it 😎
