Medtronic interview questions

Was brought through a phone interview about 2 weeks after applying that went very well and was brought in for an in person interview. Talked with many people during my visit and it seemed to be going well and they kept wanting to show me more. When the interview/visit finally ended I was very enthusiatically told that i would be recieving a call before the end of the week. I never recieved a call and all follow up communications (through email) were met with either no resposne or with aloof sense of not knowing who would be making those decisions. 2 months later the application online shows the postiion as filled without ever being told there would not be an offer.
