Initially contacted by HR rep for 30 min. screen phone call. Usually, they have established interest from hiring manager on your background if you applied via website. Hiring Manager called the next day for exploratory phone interview. He had a hard stop due to a meeting, but called back to interrogate for an hour. He seemed confused about what kind of skills and experience he needed to hire and was abrupt. At interview, you can see CVS Caremark has a couple of different cultures (retail v. analytic) going on during transition @ HQ. Hiring Manager had little experience in healthcare, so did not relate to my skill benefits. Manager interrupted a lot, so not a great personal impression. Seemed unable to commit on hiring decisions. CVS is a place where people hire people like themselves; seems like a challenging place to work, with turnover and plenty of artificial stress.
