done by outside recruiters who are not very knowledgeable about the actual job duties

Very simple process. After the phone screen with the recruiter, an interview with the hiring manager was scheduled. The last step was the group panel interview. Both interviews were mostly like conversations. I felt very comfortable. Ask good questions related to the job and the skills it takes to do the job. It's always good to look up the websites for Aetna and CVS beforehand to understand the products and services better. Ask questions about the websites. Understand the job and have a good answer prepared for why you want to do the job or why you want to work for CVS.
