I would recommend trying to arrange even a chat with a couple of community pharmacists if you can't get any actual full-day work experience, just to find out the realities of day to day work in a community pharmacy. It's very busy and some people don't like the repetitive nature, others however, like the regularity.
Some people really hate the 'healthcare in a retail environment' and don't like the idea of having a degree and working in a shop. And it's important to remember 60-65% of pharmacy grads end up in retail pharmacy. You don't want to spend £40k and 5 years of your life then find out you really don't like what you trained to do.
In the large chains and the supermarkets, your managers will usually not be pharmacists and may focus more on the retail side and targets, which some more clinically-minded retail pharmacists can find difficult to adapt to. But a business exists to make a profit.
But let's finish with some positives!
There are lots of new jobs opening up in GP practices and PCNs, and all new pharmacists will now qualify as independent prescribers after completing the degree and foundation year, so there are lots of new opportunities on the horizon hopefully, if the government will engage with the profession on having a prescriber in every pharmacy soon.
