With interviews coming up soon, I thought it would be good to ask here for any tips on how to do well in medicine interviews. I've been told it's important to read up GMC guidelines, ethics, be able to reflect etc. which is good. However one topic which I'm not sure about is the NHS - such as the role of different workers (healthcare assistant, oncologist etc). There are a lot of roles so is there anything specific that I should definitely know about healthcare roles in NHS?
