I have worked in industry, hospital and retail - Ok I get sacked a lot....... :evil:
I would say hospital is generally more interesting, as you need to use more of your clinical knowledge, and can specialise in one area of pharmacy (eg renal pharmacy).
There are good stores to work in though, and there are people on the forum who are happy with their retail career.
If you come to the UK you could start in retail, and look for a suitable hospital role when you are here.
In general we still seem to be short of pharmacists in the UK (from my experience) and you would easily get a job in retail, as well as a better starting salary.
