Are you going to advertise that you stutter at the start? I want to say that stutter doesn't hold you back from speaking your mind, you can still speak your mind, you'll just do it while stuttering. But I understand there are times where we cant even stutter our words out, even if we wanted to. Advertising might help and could be a good experience. I'd try to resist time pressure as much as you can and don't try to be fluent during the interview as it can make the pressure and fear worse. Good luck!
