Hi,

Do HR still practice offering candidates salary package from their
previous payslip?

Market is offering a higher amount but my salary
started out as below market rate. I noticed most jobs used that as reference.
I noticed my pay is 35% below market rate for my experience and most companies
offer like 15%-20% max.

When i asked for 35%, HR are not accomodating. What is most effective method to convince them otherwise or any website do professionals use a reference to nego better pay?
