My first job I ever got I stuttered through the whole interview and they still hired me. The manager even asked if I was nervous or something and I told her yes but I also have a stutter that I’ve had since early childhood. She didn’t make any more comments after that point about it. I say do the interview, even if you completely blow it and they don’t hire you, oh well, not like their opinion of you matters since you won’t be working for them anyways.
