Either disclose the fact that you stutter or go into it knowing there’s a likelihood that it’ll happen so when it does occur you’ve already given yourself the mental clarity of getting past what could be a very anxious nerve racking period. Also try to take some heat off yourself though yes it is an interview when the chance comes to talk to the interviewer ask them questions about themselves or in general cause people love to talk so even if you bomb the interview you may leave a lasting impression on that person for a callback. Side note from psychology: you should aim to get in earlier in the day or be one of the last that way you’re getting their attention first in the morning when they’re most attentive or getting their last vat of attention at the end of the day ie becoming more rememberable even though us stutters are hard to forget anyways lol Good luck bud!
