Dear bhavin Raja. wonderful to see your profile. it seems to be you are having must thrust to work in core areas where after long experience people use to work in the core areas like in HR. general administration cannot be given immediately. it happens only after time office,payroll, recruiting, etc.
I can suggest you something like retailing is one of the core area in the marketing if you are interested you can join at Wellingkar Mumbai, IPE hyderabad offers with offerdable price.
further if you are still affordable ISB hyderabad or mohali also better if you are able to getin. try for ISB. your aspirations full fill. best of luck. feel free to come out.
further, still you are affordable. takeGMAT /TOEFL later you can get more better options.from best b-schools from US/UK
