Dear Ruhi,
You already have experience as an admin/relationship officer, so you would not be considered a fresher in HR. However, you also have experience as a trainer, which is in demand in the ITES industry. You can continue as a trainer if you are interested. If you are keen on HR, consider joining in recruitment in the ITES sector, as you have the ability to screen candidates effectively. Initially, the pay may not be high, but after gaining a year of experience in recruitments, you can aim for positions in reputable companies focusing on core HR activities for better exposure.
You do not necessarily need to have an MBA/PGHRM qualification. If you possess good PR skills, are a good counselor, and have empathy towards people, which are essential qualities, you can succeed. Simultaneously, consider completing a course in HRM. In fact, I am a science postgraduate with professional experience. Only after working in recruitments did I get an opportunity in core HR. Trust me, it requires a lot of patience and determination but is definitely not an easy task.
ALL THE BEST :) :) :) Hope this advice is helpful to you.
