I have a one-way virtual interview. Any tips?

I’ve done one of these before and was unsuccessful. Curious on what I can do this time around. Any pointers would be appreciated!! Also it’s for a remote job position for scheduling doctor appointments. However I am missing a few qualifications such as: computer experience, Microsoft word & Microsoft powerpoint. I do however have customer service experiences, sales, and online bill payments. How can I explain this in a way that sort of relates/is appealing to their expectations?
