I apologize for this might sound trite, but what do YOU want; forget what everyone else says, what do YOU want to do?
I want to continue going for interviews for HR positions. I have worked in HR for the last 18 months and i also studied HR at uni.
I am glad you wrote back :-)
So, when they call you again, thank them for thinking of you and tell them you that although you are flattered, you are pursuing other opportunities.
Then... do what YOU want to do :-)
