When applying for courses:
Different institutions have different approaches. You may have a traditional 1-to-1 interview with a panel made up of admissions team member/s and relevant professionals. Or you could have a mini multiple interview (MMI), which consists of several question stations, each with a different focus. Some may involve role play or manual dexterity tasks and you will have around 4-10 minutes at each station. Other courses may use assessment centre approaches, which might involve group work and individual interviews.
Check with each course when you apply, as most include this information on their web pages. However, on all courses, expect to be questioned on the NHS Constitution and NHS values, your work experience/work shadowing, and your knowledge of the relevant profession and your commitment to it.
An understanding of latest developments in health and medicine can be very helpful for applications and interviews.
