Hi! I do not want to scare you by writing this, but I just want you to be prepared. I had a wonderful experience with one of my interviews and it was exactly how others here have described it...my interviewer was just interested in talking to me and hearing MY story. We talked a lot about my activities section, and not even in relation to medicine. It went really well.
HOWEVER, my other interview was a disaster. The interviewer drilled me on ethical questions (& very specific details regarding them, ex. state laws/procedures), current world events (specifically world, NOT USA and NOT covid related), and 'traditional' pre-med activities I was lacking. It was a disaster and I honestly think I will get wait-listed because if it- I fell flat on my face. I think this was an outlier, especially because my other interview went so well and went like others have described. But do yourself a favor and at least brush up on some common ethical topics and world events- hopefully you won't be asked anything of the sorts and then you can come back here and laugh at me for suggesting it. Good luck!!
