Salary is also to be related to qualifications & post qualification experience. For example, if someone is MBA - HR & has an experience of 7 years after doing his/ her MBA, the remuneration may differ compared to another HR person who is non-MBA, but with same experience. In fact, it may different even for those who are MBAs, but from different institutes (say, IIM & a private college offering PGDM -HR, equivalent to MBA).
In addition to the above, there will be difference between large, medium & small size companies within/ across industry verticals. The picture may further differ between public sector, private companies (listed/ non-listed) & the Govt. sector.
Ramya, your query, therefore, needs to be more specific & focused. If you are an HR person, asking such questions is a matter of concern.
