IMO: don’t waste your time/money going to trade shows.
If you are looking for entry level positions at pharma in the UK sign-up with as many recruitment agencies as you can. Not a pleasant experience, but they will find you a job if one exists.
Where is she based? Hopefully the answer to this is either Cambridge or the Thames Valley.
What does she actually want to do? Sales? Or work in a lab? Or just interested in getting into the industry at this stage?
As Nosedive has mentioned – being a Clinical Research Associate is a good “in”, but these days, most places want you to be an in-house version first (basically glorified admin), but within 6-12 months you should be able to move forwards. Talk to the big contract research organisations (Covance, Quintiles, PPD, PRA, Inc) as they all hire this type of person fairly regularly.
If she’s going to have a PHD, I would be looking at “Medical Scientific Liason” (MSL) or “Medical Development Associate” (MDA) type roles. More scientific in nature – they sit between sales and research, and they are really an expanding function at the moment. Again, agencies will be able to help you find companies that are looking for these people – it’s going to be the pharma companies themselves, and they are probably advertised on their websites as well.
If you let me know where you are based, I can give you some names.
