I tend to not stutter much at interviews since I tend to sort of "put on an act" of trying to seem more confident and professional than I really am. It really helps if you come into the interview prepared with potential answers so you don't get caught off guard, get nervous, and stutter worse. My general rule for telling people about stuttering is if I think I can be fluent, I'll try without telling them, but if it gets bad, just say excuse me I have a stutter. Look into medication for big speaking events like interviews or presentations. I take atenolol which helps a little, but you may want to look into something stronger such as atvian with your physician depending on how several you stutter is - be sure to not start using them for everyday speaking. Good luck
