All the interviewer in my career except 1 have been totally cool about my stutter. What can help you is to remain calm and before your interview just take deep breaths to calm down. It's okay to stutter. What people think of it is upto them and beyond your control. Just give your best shot. I usually repeat the phase "Fuck the Stutter" in my head before an interview. It's stupid but it helps me calm down. 😂
