What do I need to do to become a pharmacutical/med device sales rep?
I think it’s safe to say that for these two industries it will be extremely hard to get a job unless you have a university degree. You can enter through either business administration or science background. Check whether in your country there are some organizations offering certifications you can obtain to boost your profile e.g. in the US you can do one at the National Association of Pharmaceutical Sales Representatives (NAPSR). The other parts are really no-brainers and apply to any industry: try to get sales experience and network.
