I think I got my first (and only) job because at the interview I told my employer, at an educational establishment, that one of my main interests was football (it turned out he was obsessed with the game, more interested in it than in academic affairs). Also it would only cost half as much in salary to employ me, as a 22-year-old, than the person I would be replacing. I still ended up having a nervous breakdown though, trying to fit in with the rules and hierarchical structure of that job, and trying to relate to and deal with people in general.
Also, despite the fact that I apparently scored higher marks, in all of the seven written papers of my University entrance exam, than the thirty-odd other candidates, I was later told that I almost talked the selection panel out of offering me a place at my interview, by either saying the wrong things or not saying anything at all

At least you're aware of the issues, Cockroach 96, and can think about some strategies to deal with them. When I was your age, and for many, many years after, I couldn't make head or tail of my 'issues' and had no conception of how others saw me.
