pipistrelle,
I think they don't want people with your kind massive experience.
They know full and well, that the T&C's they're offering is nothing to endure over a longer period of time. Hence, they know you'd be leaving at the first opportunity you'd get.
Given your experience, that could happen just about any day now.....
They want people that they know they've got "by the b*lls", so to speak.
