In India I don't know why but most of the HR person usually ask about previous pay. What's the point of asking this?
This is not duplicate of How to respond to a direct ask of salary earned and expectations? as I am looking for reason on why HR would be concerned about previous salary.
Is it because they wan't to hire the applicant at minimum wage possible?
if that's the case then would it be fair in a company if two people who are doing the same work are paid very differently just because one person's previous salary was less?
