Career Advice About Figma

Hey Folks, I have a System Design Interview with Figma. Is there some fundamental material that I can start from?

I've heard a lot of discourse about how is a game changer and a huge deal for Figma because of it. I hear people say this is disruptive and an excellent case study in product. I've kinda used figma here and there but never really for a lot.

Thoughts? Is it something useful for you? Is it actually a game changer?
