No institute can give you the practical knowledge you are talking about. Actually i Feel you are on the right place right now. On cite HR you can get answers to all your queries regarding the same also you can study the same while working . your company must be registered in PF, ESIC etc. You can learn the same from the person responsible in your organisation. Its not about what is your job profile, being an HR you know that if you can answer the questions in interview then you can do it or vice versa. But, Believe me Generalist profile is not only about ESIC & PF there is much more to it. Still at beginners level you can get on with it. All the best.

You need to keep brushing your knowledge... Your answers must show eagerness and energy. The Statutory Job is not the only Job... So You need to project your strengths and then face the interviews. You may be applying for jobs, where the experience is 1+ years. So they will expect you to know the basic... Brush them up....
No amount of institutes will be able to give you particle training.
So update and keep learning and keep growing...
All the best
