Had a similar conversation with an HR recently...Yeah. I know of someone that might be interested, but seeing as there isn't a range it's pointless even recommending the ad.
Plus, I'm almost willing to bet that the first requirement from their side will be a payslip. Dark and arcane practices being pushed here. We can't tell you, but you must tell us. Pull the other one.
HR: "We've got this role..."
Me: "What is the salary range?"
HR: "We'll send you the job spec, send us your payslip then we'll take it from there."
HR sends the job spec, I look at it and respond as follows: "This role is junior compared to my current position so I won't be able to pursue it..."
No payslip sent.
