I have a misdemeanor from the week I turned 18 (~7 years ago). It was dismissed, but is still on my record.
I am going in to this next cycle knowing I have that red flag on my app. I think it would be naive not to realize that it will negatively impact me However, it is what it is and the most I can do is own up to what happened and show what I've done since then to be more than my stupid 18 year old self.
I doubt that really helps your question though, since I haven't applied yet.
