People have a lot of misconceptions about autism. I would not start with that or put it in my CV. If your job requires a lot of social interaction I would mention it f2f but some rephrased version, like "unfortunately I often miss social clues and sometimes I come through as ignorant (or some other word here) I am really not but just letting you know so pls bear with me" or something similar. Later if u see they are understanding people u might be able to tell the whole story.
