If you managed to obtain interviews but unfortunately no offer from them, you should be focusing a lot more on your interview technique. Unfortunately, interviews are one of those things on which not enough importance is placed on and students do not prepare for enough. Like the pre-interview stage of the application process, the interview stage itself is different in each university. Most universities assess candidates based on standard MMI stations but others have their own unique style, the common denominator between them is that they all test qualities you should have as a medical student, such as empathy, communication skills, team working skills etc. Ideally you should obtain feedback from universities regarding your previous interviews and they should give you a general idea of where there is room for improvement. Focus on your weaknesses when practicing for interviews, so if for example your performance in ethical stations was weak, you should be reading up on all the standard ethical scenarios interviews can present, you should be learning about the medical ethics pillars and you should be trying to discuss it with anyone you can to try to deepen your understanding of the concepts. If your communication skills were lacking try to put yourself into situations where you must interact with people, be it getting a job, volunteering, peer tutoring etc. At the end of the day you should be very comfortable talking about or demonstrating these attributes and skills and you should also have examples and evidence to demonstrate you have them; All of this is achieved by practicing as much as you can, whenever and wherever you can.
