I thought you were talking about the OCP exams.
If it's just questions from a company, then I have no idea. There are thousands of pages in the manuals. They could ask anything.
If they are looking to hire students, then they definitely aren't looking for experience, so there is a limit to the skill they can expect. I suspect they are just going to ask some random things, not expecting you to know what the answers are, but seeing how you react to the questions. By that I mean, can you reason out an answer to something you've not experienced, without just BSing.
But really it's impossible to know what they are going to ask.
