I would like to know whether you are looking the career into recruitment or generalist. You are mentioning both as recruiter as well as Payroll.
My suggestion is it is better you dig through the discussions in the CiteHR you will get all the necessary information. If at all you have any doubt in particular then you shall post your query & will get lots of responses from the seniors.
Thank u so much for the reply im looking my career into recruitment only not as generalist my doubt is , Is it important the hr has to know about payroll in recuiter position i want to work as a recuiter if yes how should i have to learn because in distance education its not possible
