Just popping in to say that tool will only be useful for half of your interview for UTK. I'm not solid on all the details, but while they're keeping the conversational interview portion, they're also adding an MMI portion last I heard. Take that with a grain of salt because sometimes these things don't get implemented immediately, so it may be that they're not adding it in just yet. I just figured I'd give you a heads up in case they are.
I will also say they do tend to interview most of the TN residents that apply - usually around 87%. That being said, your interview and where you will fit into the class they are building as a whole is very important here. The interview is a third of your total score (if you haven't looked at the selection process breakdown, you should, though with the quick turnaround I feel like they may have made some alterations). I wouldn't dwell too much on the numbers though. Just go in there and be you and show them why you belong here
