As long as you can show the interviewer what you are getting yourself into by doing medicine, your lack of clinical experience won't matter much. Clinical experience usually shows dedication to the field of medicine and it also provided you with an opportunity to see first hand what your future may be like. It is really to distinguish the understanding for medicine from what is shown on TV dramas.

Since you changed from Finance to medicine I am sure you have a good reason to do so, talk about it and why you are passionate about medicine.
