I got a phone interview from the SF bay area HQ and the Atlanta group in the same day for the MBA intern position. I was interviewed by the director level person of both areas. The SF site lasted about 30 minutes and the Atlanta site lasted for 15 minutes. The SF guy asked questions like why McKesson, why finance, what is culture of your current company like. The Atlanta guy asked tell me about my experience and he talked about different intern opportunities wit his group. Both guys didn't give specific answer about the intern position entails. The Atlanta guy interview was via conference call and I can barely heard what he said.
