I can only tell you what I've heard from recent graduates - they take their board exams as soon as they can after graduation. The state board is trying very hard to process them, but notification can take 60 days. Then, you have to send your money & they give you your license #.
In my case, which may not be applicable at all - I took my board exam 2 weeks after I graduted, which meant I took it at the end of June. I got my pass notification in August, I sent my money by Western Union (now defunct!) & got my # the next day.
But, I can't tell you the process now. Remember though - it also depends if your employer want a pharmacist. If all they want is an intern...you may find yourself looking for a job.
