Very conversational interview. Consider all relevant questions like why medicine, why here, why DO, etc. Go to the interview feedback for LMU-DCOM and go over most of the questions reported there if you want. But the DCOM interviewers just want to know who you really are, and confirm that you have all the qualities you stated in your personal statement.
For the interview feedback, go to the homepage of SDN, under the tab "resources" choose "schools and interview feedback", and then choose DO schools and then LMU-DCOM. You will find many interview questions reported there.
