As I was getting ready for the interview - I had to change into interview clothes and do make-up/hair here - H complimented my outfit. Then he indirectly tried to sound me out about my plans for the evening, saying he didn't have any and was 'open'. I was diffident, saying that it depended on what happened in the interview, plus there was a movie I wanted to see.
My take is he's asking you out without haveing to ask you out. I think you are wise to be concerned about the rejection. Play it cool until you get back from your interview, then, just as a passing thought, maybe we should go to a movie....
