As a fellow man with the same disorder, in my experience what’s best it’s just admit it. Yeah. Imagine you going into that interview and starts talking without saying you stutter, in my culture we call it like stepping in with a monkey in your shoulder. I suggest you to just “come clean” right off the bat and say you stutter, and it won’t affect your actions and results. From here I trust you will know what to do. Best of luck!
