Here, we had to wait until we matriculated and got a letter from our school to take to the Board of Pharmacy for our intern license.
However, since I didn't have a job in pharmacy, the summer before I matriculated I contacted a recruiter from one of the retail chains and explained that I was matriculating in the fall and could I be hired in some other capacity in the interim (i.e. tech). This way it got me in the door and used to their computer system, etc whil eI had time to devote full time. It worked, that first recruiter emailed me back immediately and within 2 weeks had a position for me. It was nice to not have to look for a job once school started. Don't know if hospitals would do the same thing....
