Zoom is fairly intuitive (at its basic level) and relatively easy to get started with (even hosting your own meeting).
However, it also has lots of features (some hidden) and there are many tricks to using it effectively, as well as other tools, programs and apps that you can use with it.
And nothing beats trying out its features (such as breakout rooms and screen sharing) with a small group of people ... BEFORE you do it live with your own customers/clients.
