At the beginning of the interview, they may directly ask if your parents or relatives are medical. Either way, the key thing is to show that your particular status is an advantage to you as a potential medical student: if you have parents who are medical professionals, state that you have been able to experience the busy personal lives of doctors first hand. It may then be a good idea to cite some personal anecdotes to reinforce this fact, such as having to see your relatives occasionally miss family gatherings to go to attend emergencies or having to study late at night in their free time to pass professional exams. On the other hand, if your parents are not medical, emphasise that it has given you the freedom to explore many other careers and not feel obliged to become a medical professional. If you are asked to comment on your understanding of a doctor’s personal life, you can share some of observations you have made while on attachment or volunteering. You could also discuss some medial autobiographies, such as Trust me I’m a Junior Doctor by Max Pemberton, Fragile Lives by Stephen Westaby, Admissions by Henry Marsh, This is going to hurt by Adam Kay or In Shock by Rana Awdish.
