FSH Program Application?

Hello. I just received my acceptance to USC and was invited to apply for the FSH (Freshman Honors Science) program. At the end of the application, there was a section for short answers/essays. I was wondering how long these essays should be and if USC is looking for anything specific in these essays.
Also, how competitive is admittance to this program? I heard that students who get the invite to apply are practically admitted but I’m not sure if that’s true anymore.
Sorry for the lengthy questions; thank you everyone for your help!

The way a few other admits and I on the group chat saw it was that it was a pretty low-key application.
