How to condense academic CV in one slide
I would treat it as a bullet point summary of your accomplishments:


PhD/dissertation
Notable experiences (e.g., teaching, internships, and professional positions, but not the typical TA/RA positions)
Awards
Summary of publications (e.g., "8 publications in venues such as A and B")


There are no standard rules for this. The goal is to convince them you are worthy of a job, so eliminate any noise and only provide the highlights. They can refer to your actual CV if they want more details.
