grrrr
so have got a shortlist having read through lots of CVs
have a chat with a few of them
one says outright she doesn't want a job where she pays tax (so she's off my list) - she was the one best qualified and the most suitable
second one's visa runs out too soon for my liking
3 and 4 are both doing nanny work already where, essentially, they are being treated like au pairs (so yet again, not paying tax).
I refuse to pay like that so I've had to say no to them too.
