As someone who has been told they couldn’t be hired because of my stutter during interviews, I would only disclose it in the interview if you end up stuttering. Jobs can easily discriminate now by just not hiring you. It will work out though and you will find somewhere to work trust me. Getting promotions and keeping work is its whole other battle with stuttering. I see people saying they have a mild stutter or severe stutter, I feel like mine switches back and forth depending on situations, moods, and just rhythm cycles. At times it’s so terrible I can’t get any words out and for lengths of time I am almost fluent in most situations.
