Hi... I just wanted to say sorry that you feel like that and also that there is help out there! Interviews are nerve wracking no matter what, and I find myself stuttering a lot too when I do them. When I had MMI interview I started prepping weeks in advance through mock interviews so I could avoid any stuttering or nerves. I don't have a genetic stutter like you may, but I wanted you to know that you shouldn't let it stop you from doing well! I was able to stimulate mock interview experiences to get more comfortable by using myls ai. Maybe that will help you get better the more your practice.
