Matt you have done really well going to the interview, i know how hard it is with your AS. It must have been be so daunting for you, but you did it!
And well done trying to speak to the people outside,even if it was only to say hello! your a star!
Well done for getting through it, interviews are just awful. Even if you just said 'hello' to people its a good start. Personally I think there's nothing worse that someone new coming in to work so full of themselves, just taking it slowly is the best way and let them get the know you gradually IMO. Go get your new Pokemon game, you deserve it.
