There's just too many of you out there. Honestly, most interns are equally qualified. Inside information is going to be key...we've periodically hired interns without even advertising positions publicly because we've trusted the person recommending and didn't have the time to formally post.
In order of priority, this is how I would sort the pile of CV's/resumes.
TOSS: too freakin' long, your CV shouldn't be 7 freaking pages of fluff unless you're some previous PhD research guru.
TOSS: poor formatting and spelling/grammar errors
TOSS: incorrectly addressed cover letter (wrong hospital) or other glaring error (saying you love working in a burn unit, and we don't have one).
Automatic advancement to interview: personal recommendation from current trusted pharmacist/other work colleague from other institution > school of pharmacy faculty with good working/personal relationship with me > current resident/previous resident
Will give additional benefit of the doubt: Recommendation from current technician/intern > from other hospital employee
Special cases: Family and friends of Pharmacy Director on up the hospital hierarchy
Top of the pile: previous hospital technician work history
Next under that: previous retail technician work history
Third factor: Involvement in school activities (mostly because I want an intern that's actually interested in lots of things, we use interns for special projects all the time)
Additional factors I would weigh: previous BS/BA degree and pedigree of school (Top 50 > community college only), previous other work history, personal hobbies (you are putting these at the end, right? I don't want to hire a drone).
Things you might think would count, but don't really impress me: Letters of recommendation from anyone I don't know and grades (unless you're failing and risk losing your intern license).
Bonus: If you manage to convince me without sounding fake that you want to pursue a PGY-1 residency. I don't want to waste my time teaching and training an intern that will eventually go rot in a community pharmacy.
That's approximately the screening process I would use, the interview is mostly for fit and personality, the stakes are pretty low for interns vs. other employees so we tend to just go entirely off the interview when decision making.
