Well, for 1, I've seen a couple people get away with, "Holding
your job", but you'd need a certain style and audacity to pull it
off.
As for the second, you're going to need to do your research, find
out exactly what the organisation does and how it does it, and what
you can do or have done that fits into that picture. Unfortunately,
it's all on a case-by-case basis, so that as precise an answer as I
can give you.
