Dear Pallavi,
Generally, there is a feeling among people that work experience in HR in a BPO may not be considered in the future when applying for a new job. However, this is not the case in reality. It will be taken into consideration, but you should be very clear that your experience is in HR and not in other functions under the umbrella of HR.
Strive to introduce new HR practices and enhance your knowledge in your profession. If you are seeking to broaden your skills, I would suggest exploring opportunities in the Manufacturing Industry.
Regards,
M. Kannan
