Agree, they should see you beyond your fluency and hire you. Yes all of us want to be fluent in the interviews and everyone has their own level of stuttering, some can hide it and some can’t. For example, I gave a tech interview 1 hour ago, and for some reason I stuttered quite badly (even though I’ve had smooth interviews in the past), but all my answers were correct. So if they reject me I will know it’s because of my speech today and I’m okay with that because I don’t want to patronised later when I join them, just because I can’t speak fluently like them. Sometimes it feels bad, but you need to keep moving forward and your head raised high. Keep working on it and good luck!
