Not sure what country you're in. Lately I've been disclosing that I have a stutter that gets heightened in situations such as an interview. Depending on the culture around stuttering where you're located, this might not be so helpful. It took years of therapy to be confident enough to say that at every interview. Having "the elephant in the room" addressed out in the open allowed me to focus on using my skills, especially slowing down my speech, taking as much breaths as I needed to fully answer the questions. It removes the extra burden of trying to hide your stutter. I wish you all the best with your interview.
