A good trick that helps me in interviews is that I just tell them at the beginning that I have a stutter (not apologetically but in a matter of fact way). I mean, they will notice it eventually in the interview and I’d rather be in control of the situation than have them be the ones who bring the topic up or even worse, stay silent and think I’m just nervous. I’ve tried propranolol but never worked for me. Clonazepam always does the trick but don’t start taking benzos unless you consult your doctor. It’s a slippery slope my friend. Also, what is this DAF application? Never heard of it. Good luck. You got this.
