I agree. Maintain eye contact (even during moments of stuttering!), keep your shoulders back, if you’re smiling as you talking and you start stuttering- it can make the biggest difference in the world if you’re able to keep that smile or return to that smile right after the moment of stuttering has passed. All those things tell the interviewer that your speech disorder does not affect you, and in turn, your work! Good luck! And hey if you ever have a way to prove that you were passed over for a lesser qualified applicant due to your stutter, sue them! Not just for you, but for the future people they will discriminate against.
