You can choose a resume with or without a cover. I suggest you make a simple template with your own school emblem. My own resume is very simple, just a piece of paper. I can send you a template to see.
Be prepared to introduce yourself, as well as things that you may take in the western comprehensive exam during the written exam, and you may also take exams on film photography and technical topics. Some hospitals are all multiple-choice questions, and some hospitals have short answers and questions and answers. When you enter the hospital interview after the subject interview and written test, you should introduce yourself and some problems that have little to do with your major. Just try to express your determination to stay in this hospital.
Waiting for a job will take a long time, and you will feel a little discouraged after being rejected. But keep going and wait patiently for the hospital you are satisfied with. Don't give up your first job, sign it. You may stay there in the future, so think carefully.
Finally, I wish you good luck in finding a job!
