Great community, ton of incredibly smart and helpful people. Including ones that wrote the books everyone suggests. I'm not on it daily anymore, but spent more time there than I did on TexAgs for a long time.
I echo everything nwspmp said. If you are in a technical role, then start learning how to think like a manager. You're not trying to solve problems as much as make risk management decisions for a company.
There are A LOT of processes. Learn them and know them well, because they will most definitely help you decide between a great answer choice and the perfect answer choice.
I'll add that 11th hour was a great book for the last couple of weeks before the test. It's not very in depth, but a good review to make sure you are not missing any topics.
The discord I posted has a test bot in one of the rooms that asks questions around the clock. They were written by people with a CISSP, so a great help.
Oh, my single best piece of advice to people when they ask how to tell when you're ready: if you can teach someone else a concept without resources, then you know that concept enough. Now just repeat it for all of the topics.
It's a CAT test. It'll figure out your weakness and hammer it over and over. So, it's not good enough to load up on 6/8 domains and think you're good.
That turned into more of a brain dump than intended. Gotta love pointless meetings.
