I'm just concerned that I'll be on one of my "bad" days and will mess up an interview because of my stutter. I'm mostly looking for advice on how to deal with general stuttering and interviews. I'm in a top 5 applied mathematics program and am looking for an internship right now. I feel like I am qualified on paper but that interviews are hit and miss due to my stutter. Also, how have you managed to hide your stutter from your colleagues?
