Immunology - Area Manager

I have noticed a lot of Area Manager positions have just been posted. I am going to ask for some honest feedback. I have 4 years in Immunology and our company was bought. I do need a job that's why I am asking some question on here before applying so honest feedback would be great.
1. What is the salary range?
2. How big are the "Area Manager" territories?
3. Bonus potential? Goals achievable?
4. Calling on Physicians or Hospitals?
Thanks for honest feedback.
