Who knows? Again, there are 1000's of hiring managers with Aetna. You needn't worry what kind of tree you would be, if you were to be a tree. You may be asked why you want the position, what makes you the best person, etc. etc. Public sector work is a growing domaing at Aetna, so knowing about medicare, medicaid might be good, depending on the position you are seeking. I asked interviewees to complete a simple spreadsheet regarding weighted averages, when I was a hiring manager, but very few managers do anything like that.
