How do I know if I'm ready for what the job demands?

You are not sure you are ready for what the job might ask of you. That uncertainty is heavy, especially when you cannot fully know the demand until it comes. But notice this: the ones who worry whether they are ready are usually the ones taking it seriously enough to prepare. The frightening ones are those who never ask. You cannot feel ready for something you have not faced, and no amount of imagining will manufacture that certainty in advance. What you can do is train, prepare, and trust the people beside you, and know that readiness is less a feeling than a foundation you build and then rely on when the moment comes. Confidence follows action; it rarely arrives before it. So stop waiting to feel ready and focus on being prepared. Master the things you can control, your training, your gear, your part of the team, and let the rest be met when it comes, alongside people who have got your back. You will likely never feel fully ready. Almost no one does. You just have to be prepared enough to act, and you can be.
