In my interview I think I definitely sounded weird but it wasn't quite apparent that I had a stutter. I paused a lot trying to think of what I was going so that I wouldn't stutter tried to mimic confidence as much as possible. I definitely remember slurring some words and some slight repeats but no serious blocks. Confidence is key in interviews people want to hire someone who is confident in they're skills and know they can get the job done. By the sound of your comment you're already confident and leagues ahead of anyone else (people who have a stutter or not). In high pressure speaking situations like this I think we perform better than the average person. This is because almost every speaking interaction we have is a high pressure one (asking for help at a supermarket, making an ordinary phone call etc). So we know how to deal with the feeling, make a note that it's there and yes it might affect our speech or it might not but we're not going to stop. However the average person does not get that experience of performing like that very often, only in very rare situations like an interview or presentations. I've watched and given plenty of presentations at university and I see people's confidence drop or them freeze up when asked the simplest question. Make sure you make eye contact and just know that you can do it. Even if you do stutter during the interview so what? If you're answering the questions correctly in a calm and confident manner then why care?
