I am not one but some friend's son is a Pharmacy student and tried to get a job at a pharmacy this summer and had zero luck. He has 4 of his 5 years done on his pharmacy program at one of the top Pharmacy programs in the nation and couldn't get a job.
There could be a few reasons for this.
For one, as we mentioned below, most want experience.
But also, to an employer, your friend is going to be a pharmacist soon. Companies pay an awful lot of money to train people, they don't want to lose him in a year. Perhaps they're looking more for long term tech help.
Also, you'd think maybe they'd just keep him on as a pharmacist, but it could be that they're saturated with pharmacists but need techs. This could be a trend (and one I've heard of happening) - ie hiring less pharmacists but more techs.
Which brings me to why there's a need for national certifications and such. Medication is amazingly regulated. Again, amazingly. So if pharmacies are going to be hiring less pharmacists and more techs, presumably to do jobs that were traditionally done by pharmacists, then there needs to be some formal training. Look at the medical mistakes reported with pharmacists (and in fairness, nurses, doctors and other health professionals, all of whom have taken huge steps in the last decade or so to prevent them from happening). When something happens with a tech, who's working under a pharmacist's license, it's a big problem. Having techs certified, they'll have their own training and, at least to a degree, ie within their job description, they'll be working under their own certification.
I'm sure there's a lot more to it but further thoughts will have to come from pharmacists. ETA this one's from Canada, but an example of thoughts from pharmacists on their roles and techs'.

BTW, many hospital pharmacists who oversee operations are practicing at the PharmD (doctorate) level, at least where I work. So things have been changing in the pharmacy world, and with good reason. We all want to have our medications given to us safely.
