Welcome to Cite HR family.
With an Engineering degree you are already having an experience in HR.
Whatever course you take should be having HR as one of the main subjects.
Any full fledged HR course would be desirable.
As of now in my view you are in the right track.
If you have decided to study, study and do well.
When you finish studying your line of experience and the recent qualification
will not be different. This will be a plus point to you.
Cite HR has many such posts like yours.
Search them and get more details before taking a decision.
