Here's a realization I think many stutterers try their hardest to ignore. To someone unfamiliar with stuttering, it's very very weird. It looks like a mild seizure. The day of my interview when I pulled in to visitor parking and rolled down the window, after about 5 seconds the security guard asked "Are you okay?" to which I overcame my block and said yes and carried on. (Actually, that may have calmed me down a bit and I stuttered less when meeting with the recruiter.) So it's useful to explain that you stutter before the interviewer draws their own conclusions. After that they expect you to stutter, so if you do they won't be alarmed or inclined to interpret it as nervousness or not having the right answer. That's how to remove the interviewer's expectation for you to be fluent, which relieves a ton of pressure in general. A bigger difference will be getting past your own struggle to be fluent, for which you'll have to become comfortable with stuttering. I'm sure you've noticed blocks get worse the harder you push at them. You tense up more as the situation gets more awkward. If you can stay completely calm when that happens, it gets easier to back off and reapproach the word and carry on the conversation. I only discovered this several months ago when I started going to NSA meetings, and those have been great practice. I love my job, even though it involves giving a presentation every once in a while. It's a great talking point and I'm pretty open about it, just not on reddit, so PM me if you want to know more.
