Yes, I've had a few run throughs of the journals promotion thing today - it actually sounds reasonably OK. The next thing I need to do is read more of their research, think of questions for them, run over my achievements in general and also read the job description closely to ensure I definitely understand what it is.
I once went for a role a bit like this within my own organisation and the interview was rather painful as it soon became obvious I'd totally misunderstood what the role was, so I mustn't project too much of an idea of this as editorial onto it.
