AstraZeneca Intern interview questions

I applied online for a spring internship in Gaithersburg, MD through their website, and got an e-mail requesting to set up a telephone interview in a couple weeks. The interview was a 15 minute background review... seemed to be from a staffing agency instead of HR. Just asked general questions pertaining to my background relevant to the position (lab experience, etc.) and why I wanted to work for MedImmune, then said I was good and that my file would be forwarded to the hiring manager for further interviewing. About a month later I received an automated e-mail saying that my position was no longer available, no direct response from anyone in MedImmune.
