Dear Prasad, I don't want to involve myself in the discussion of your interest in HR, but I'll tell you about the activities of HR in an organization. Actually, HR activities involve coordinating with all the project teams of the organization because you have to fulfill the manpower requirement of the organization. Now, you have to set different parameters like calling skilled candidates for interviews, facilitating and conducting the interviews, follow-up, salary negotiation, joining formalities, induction, training, establishing performance standards, appraisals, grievances, statutory compliances like PF, ESI, etc., exit interviews, and relieving formalities. All the above activities come under HR activities. To put it simply, "all the activities from recruiting a person until they leave the organization."
