First of all, that's fucking illegal. They can't discriminate based on your stutter. If you have that shit in writing, you could honestly sue. I'm not well versed on the law but I'm sure someone here is that can explain better than me. Secondly, in my experience Ive just been straight up with people. If you get hired and they find out you stutter and don't tell them, it can be interpreted a couple different ways so I just tell them. Be confident about, own up to it, and people don't care. It's when your awkward about it and hide it is when people get awkward. Good luck out there and keep on trying. Side note, read Cant Hurt Me by David Goggins, dudes a machine that had a stutter and was in the Navy Seals. Alot of inspiration in that book.
