I'll be honest: the virtual one-way assessment was the most challenging format I've encountered of all the interviews I've done. This may be because I'm older and my relationship with technology is different. I seriously dislike selfies and will likely be the last person in the pre-med or med school space to start a vlog. For that reason, I felt uncomfortable with the one-way format. Even with a traditional interview or MMI, you can read the other person and see if they understand what you're trying to communicate. This is lost in the one-way interview. If you're like me, my best advice is to answer the question and move on. Don't linger on thinking you have talk more or fill the remaining time.
Regarding examples of questions, you can use what you find on most websites that cover tips on the med school interview. If you haven't seen this, then I'll recommend it as a resource:
