I did have a physics teacher in high school that stuttered but he was awesome and everybody really liked him and just liked to hear his knowledge on physics. I didn’t really even notice his stuttering after a while, even though I know he would stutter more when he was stressed. Maybe next time talk in the interview talk about how stuttering has made you a more compassionate/insightful person. It will make you more comfortable to talk about it and also you can use it to your advantage.
