Hi Sari
How is it doing as a newly hr?
Well we both are selling in the same boat the only difference is employee strength in my company is bit large.

I am too waiting for the seniors for the reply anyways someone has given the hierarchy level in an HR which is as follows
1. Trainee HR (Fresher)
2. Executive HR (1 Yr. Exp.)
3. Sr. Executive HR (2 Yr. Exp.)
4. Asst manager HR
5. Deputy Manager HR
6. Manager HR
and so on to the level of General Manager HR.
But it totally depends on personal performance how fast one reach to the next position..
