I think they look for other ques like how people handle adversity. I think the meaningful impact is what we do after a stutter bout. Honestly just smiling is so re-assuring that it gives a lot of people more respect for you over someone who isn't dealing with such adversity. Looking at the big picture, though stutterers are themselves worried to scale up from their stutter (and they are not alone, people just fear change in general), we do get jobs, friends, start families, etc. However much we assume the worst, in reality, the world keeps turning, with or without our assumptions. May as well assume the best. Some of the most influential people were on the verge of failure longer than most could bare. And when it comes to stutterers, there are people you can listen to as examples. On the discord there was a girl from India who became a lawyer. It was very scary for her, she was always worried about her stutter getting in the way. She persevered and succeeded! You can find stutterers in all walks of life, so do employers silently discriminate? Probably no more than anything else but the flip side is many want to see you succeed just the same!
