Are they really that different? My friend has just been told, by a recruiter, that she's really unlikely to get a job in the private sector because her whole career has been in the public sector. She's only early 30s so a bit shocked to hear that a whole sector is closed off to her.
She's in marketing, so I'm thinking is this relevant across all corporate functions. I'm aware that teachers can move from state to private, medics can move from NHS to private.
