Was hired internally (move within the same company). Was referred for this position through my internal network. Brief, initial interview with HR rep by phone and referral from former manager earned me an in-person interview. Two in-person interviews, the first with two managers (one of which is now my current manager), the second with supervisors from a closely-related group. Questions were mostly behavioral and related to background and accomplishments, primarily to evaluate whether I had a baseline of relevant experience and whether my personality would be a good fit (openness, positive attitude, sense of urgency). Process was quite painless and felt like a given, despite my lack of a mentor or sponsor in the area (Humana can be VERY political that way..)
