But they expect you to cover the cost of selection etc. without letting you know salary for the successful candidate.
It's a perfectly reasonable thing to want to know. If I have to borrow 100k from a bank it'd be more than useful to know what salary to expect to even see if it's possible to over the loan repayments.
The risk is entirely placed on the candidate, both financially an in the nature of the MPL... So yes actually, I do happen to think it's slightly arrogant.
It's a great opportunity, I'm interested to see if it's a viable option.
