I deal with it by being forthcoming about it beforehand. First impression is super important, and we’re kind of fucked in that regard, so preparing the interviewer for it takes some of the surprise away. You don’t want them to spend the first 20 minutes of a 60 minute interview getting used to the idea of hiring a stutterer; that’s when they should get to focus on your skills and personality. Of course, only let them know once they have confirmed the interview. It can still fuck your chances, though. Having a handicap that is expressed in what most people mistake for a lack of confidence, awkwardness and social fear, is a huge downside when you have a limited amount of time to convince somebody that you are the best candidate. Over time, failures in the career that arise from stuttering will also affirm and internalize the negative impressions and rejections of others into your own self-image, and act as a self-fulfilling prophecy. I have a master’s degree, half a Ph.D and a lot of various technical and aesthetic skills, and I have been unemployed for a year now, despite getting to multiple second interviews. They aren’t dumb enough to cite my handicap as a reason for rejecting me (that would make them liable for discrimination lawsuits), but it’s fairly clear when it has played a large role.
