What happens if you hardly know the girl but see each other occasionally at work/university?

Maybe ask her to a movie something like that , you know something can just be considered hanging out or dating , if it works when you're friends it should also work later as a date. To see if she's interested tell her something like "yeah we should totally see a movie or something sometime" , she'll respond " yeah good idea!" or something like that.
