I have no doubt she'd work hard but she's a nutter, an absolute control freak and hardly employable at such a level. She'll be brought down to size, sooner or later.
I don't think so to be honest. I know she has her moments but she knows it's a TV show/competition and editing probably makes her seem worse than she is. She seemed very personable and tried to make some conversation after filming.
I think in a normal working environment she'd be excellent.
