Yes, there is an expectation to speak properly, but not fluently. I have done some interviews for internships. For my last internship my employer had to choose between me and 9 other candidates. We all had to go through an interview and tests; I thought they would never pick me because of my stutter and because my internship was very focused on communication. I had to talk all day, call all day, weekly meetings, etc. During the interview I stuttered a lot, on every word.. Anyway, I got the internship and when I asked why they picked me they said I had qualities not related to my stutter and it would be an value to the workplace. They didn't care if didn't speak fluently because I would get the job done you see? Even if it takes a little longer sometimes than other people. They said they respected my choice to choose this profession and they wanted to give me the chance to prove myself, which we discussed during the interview. Over the years I started to see my stutter as a strength because we stutters know the value of words. We work double as hard to prove ourselves and that makes us stronger. People respect this when you do all the things they do even with a stutter, like a presentation.
