Hey!
Well done.... Sounds like you did do really well. At my interview they said that they we looking for 'Real people, with real personalities' From that I would guess that they are open minded when it comes to individuel circumstances. In any job there are people you like working with, and then the ones you would rather not be associated with.
I also got the impression that that research is very important to them too. So it sounds like all in all you did really well. The painfull bit starts now, whilst you are waiting to hear!!
Have a Fantastic Christmas, and let us know how you got on....
